The USB Disconnect Interrupt handler, according to specification,
is only working at HOST mode.
Samsung SoCs (e.g. Exynos4) are working at device mode, so
this interrupt is never caught.

This commit targets following scenarios for IN requests:
1. HOST requests e.g. 256B (which is a multiple of MPS = 64B).
Then NO ZLP shall be sent, since host expects exact number of bytes.
2. HOST requested 4096B, but our data for sending is 256B. In this
situation ZLP shall be send to tell HOST that no more data is available
and it shall not wait for more data. This prevents HOST from hanging.
Tested with:
- DFU gadget (various size of the sent data - also packet = MPS)
- Ethernet gadget (CDC and RNDIS)
- Multi Function Gadget (g_multi)
HW:
- Samsung's C210 Universal rev.0
- Samsung's C110 GONI

dTD's next dtd pointer need to be updated once CPU writes it, or this
request may not be handled by controller, then host will get NAK from
device forever.
This problem occurs when there is a request is handling, we need to add
a new request to dTD list, if this new request is added before the current
one is finished, the new request is intended to added as next dtd pointer
at current dTD, but without wmb(), the dTD's next dtd pointer may not be
updated when the controller reads it. In that case, the controller will
still get Terminate Bit is 1 at dTD's next dtd pointer, that means there is
no next request, then this new request is missed by controller.

In some USB composite gadget drivers, the configuration's bind function called
by the usb_add_config() calls multiple bind config functions. (for example cdc2
configuration bind function in the cdc_do_config() of the cdc2.c has two
functionality bind config functions.
- the ecm_bind_config() & the acm_bind_config())
In each functionality bind config function, new instance is allocated and
finally added by the usb_add_function().
So if an error occurred during the second functionality bind config (for
example an error occurred at the acm_bind_config() after succeeding of the
ecm_bind_function()), the instance created by the acm_bind_config() cannot be
freed creating a memory leak.
This patch fixes this issue.

ep->desc is set to NULL on endpoint disable. That means once an endpoint
is disabled it is not possible to free requests. In my target gadget I
first disable endpoints to make sure I have no requests on the fly and
then free frequests. On dummy I am leaking memory here.
Since I can't imagine a reason why it should be a bad thing, lets allow
to free requests on disabled endpoints. On removal of composite the ep0
request is removed so lets allow that here as well.
