Jeff Layton 3e4ca8bf58 ceph: fix potential race in ceph_check_caps 
[ Upstream commit dc3da0461c ]

Nothing ensures that session will still be valid by the time we
dereference the pointer. Take and put a reference.

In principle, we should always be able to get a reference here, but
throw a warning if that's ever not the case.
