Colin Ian King 8248b61b86 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.
