libceph: NULL deref on crush_decode() error path
[ Upstream commit 293dffaad8d500e1a5336eeb90d544cf40d4fbd8 ]
If there is not enough space then ceph_decode_32_safe() does a goto bad.
We need to return an error code in that situation. The current code
returns ERR_PTR(0) which is NULL. The callers are not expecting that
and it results in a NULL dereference.
Fixes: f24e9980eb86 ("ceph: OSD client")
