ceph: just call get_session in __ceph_lookup_mds_session
I originally thought there was a potential race here, but the fact
that this is called with the mdsc->mutex held, ensures that the
last reference to the session can't be put here.
Still, it's clearer to just return the value from get_session here,
and may prevent a bug later if we ever rework this code to be less
reliant on mutexes.
