[PATCH 10/24] Staging: atomisp: fix locking in alloc_user_pages()

[Alan Cox]

From: Dan Carpenter <dan.carpen...@oracle.com>

We call this function with the lock held and should also return with the
lock held as well.  This one error path is not-consistent because we
should return without the lock held.
