After dbgp_bind()-dbgp_unbind() cycle happens, static variable dbgp
contains pointers to already deallocated memory (dbgp.serial and dbgp.req).
If the next dbgp_bind() fails, for example in usb_ep_alloc_request(),
dbgp_bind() calls dbgp_unbind() on failure path,
and dbgp_unbind() frees dbgp.serial that still stores a pointer
to already deallocated memory.
The patch sets pointers to NULL in dbgp_unbind().

The drivers/usb/gadget directory contains many files.
Files which are related can be distributed into separate directories.
This patch moves the legacy gadgets (i.e. those not using configfs)
into a separate directory.
