ceph: fix dereference of null pointer cf
commit 05a444d3f90a3c3e6362e88a1bf13e1a60f8cace upstream.
Currently in the case where kmem_cache_alloc fails the null pointer
cf is dereferenced when assigning cf->is_capsnap = false. Fix this
by adding a null pointer check and return path.
Cc: stable@vger.kernel.org
Addresses-Coverity: ("Dereference null return")
Fixes: b2f9fa1f3bd8 ("ceph: correctly handle releasing an embedded cap flush")
