cifs: fix allocation in cifs_write_allocate_pages
The gfp flags are currently set to __GPF_HIGHMEM, which doesn't allow for any reclaim. Make this more resilient by or'ing that with GFP_KERNEL. Also, get rid of the goto and unify the exit codepath. Signed-off-by: Jeff Layton <jlayton@redhat.com> Acked-by: Pavel Shilovsky <piastry@etersoft.ru>
