ceph_lookup_snap_realm either returns a valid pointer or NULL; there is no
need to check IS_ERR(result).

Ceph snapshots rely on client cooperation in determining which
operations apply to which snapshots, and appropriately flushing
snapshotted data and metadata back to the OSD and MDS clusters.
Because snapshots apply to subtrees of the file hierarchy and can be
created at any time, there is a fair bit of bookkeeping required to
make this work.
Portions of the hierarchy that belong to the same set of snapshots
are described by a single 'snap realm.' A 'snap context' describes
the set of snapshots that exist for a given file or directory.
