Add fh_to_parent export definition
This commit adds support for converting a file handle to its
parent dentry. This is called in exportfs_decode_fh_raw()
when subtree checking is enabled in NFS. Defining this and
handling the expanded filehandles allows the knfsd to succeed
in handling the file handle where it might otherwise fail
with ESTALE when trying to open by filehandle.

A side effect of this change is that name_to_handle_at(2)
and open_by_handle_at(2) now support AT_HANDLE_CONNECTABLE.
