device0 was treated without checking in usbhsh_device_alloc().
but "udev->usbv" and "dev_set_drvdata()" will be overwritten
if device0 was multi-allocated.
This patch fixes this issue.

DCP data/status stage needs ureq to usbhs_pkt_push(),
but sometimes, there is no data stage.
In that case, allocated ureq was not freed,
Current ureq alloc/free pair were difficult to understand.
This patch removed unnecessary/un-understandable ureq alloc
from usbhsh_urb_enqueue(), and create simpler alloc/free pair.

Fix up the following section mismatch warnings:
WARNING: drivers/usb/renesas_usbhs/renesas_usbhs.o(.text+0xf5d): Section
mismatch in reference from the function usbhs_mod_probe() to the function
.devinit.text:usbhs_mod_host_probe() The function usbhs_mod_probe() references
the function __devinit usbhs_mod_host_probe(). This is often because
usbhs_mod_probe lacks a __devinit annotation or the annotation of
usbhs_mod_host_probe is wrong.
WARNING: drivers/usb/renesas_usbhs/renesas_usbhs.o(.text+0xfd7): Section
mismatch in reference from the function usbhs_mod_probe() to the function
.devexit.text:usbhs_mod_host_remove() The function usbhs_mod_probe() references
a function in an exit section. Often the function usbhs_mod_host_remove() has
valid usage outside the exit section and the fix is to remove the __devexit
annotation of usbhs_mod_host_remove.
WARNING: drivers/usb/renesas_usbhs/renesas_usbhs.o(.text+0x1005): Section
mismatch in reference from the function usbhs_mod_remove() to the function
.devexit.text:usbhs_mod_host_remove() The function usbhs_mod_remove()
references a function in an exit section. Often the function
usbhs_mod_host_remove() has valid usage outside the exit section and the fix is
to remove the __devexit annotation of usbhs_mod_host_remove.

This is mod_host prototype support for renesas_usbhs driver.
It doesn't support USB-Hub, and USB-DMAC for now.
