[PATCH] USB: kzalloc() conversion in drivers/usb/gadget

this patch converts drivers/usb to kzalloc usage.
Compile tested with allyes config.

I think there was a bug in drivers/usb/gadget/inode.c because
it used sizeof(*data) for the kmalloc() and sizeof(data) for
the memset(), since sizeof(data) just returns the size for a pointer.
