client: add ceph_ll_lookup_vino
Add a new API function for looking up an inode via a vinodeno_t. This
should give ganesha a way to reliably look up snapshot inodes.
We do need to add some special handling for CEPH_SNAPDIRs. If we're
looking for one, then find the non-snapped parent, and then call
open_snapdir to get the snapdir inode.
Also, have the function check the local cache before calling the MDS
to look up an inode.
