Colin Ian King b7661e9af8 usbip: vudc: fix null pointer dereference on udc->lock 
commit df3334c223a033f562645712e832ca4cbb326bbf upstream.

Currently the driver attempts to spin lock on udc->lock before a NULL
pointer check is performed on udc, hence there is a potential null
pointer dereference on udc->lock.  Fix this by moving the null check
on udc before the lock occurs.
