ceph: checking for IS_ERR instead of NULL
ceph_osdc_alloc_request() returns NULL on error, it never returns error pointers. Fixes: 5be0389dac66 ('ceph: re-send AIO write request when getting -EOLDSNAP error') Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
