If kzalloc returns null then isp1760_ep_alloc_request performs
a null pointer dereference on req. Check for null to avoid this.

   I told you there's no dereference and yet you're repeating it again. :-(

Detected with smatch static analysis:

drivers/usb/isp1760/isp1760-udc.c:816 isp1760_ep_alloc_request()
   error: potential null dereference 'req'.  (kzalloc returns null)
