exportfs: require ->fh_to_parent() to encode connectable file handles

Browse source

When user requests a connectable file handle explicitly with the
AT_HANDLE_CONNECTABLE flag, fail the request if filesystem (e.g. nfs)
does not know how to decode a connected non-dir dentry.

Fixes: c374196b2b ("fs: name_to_handle_at() support for "explicit connectable" file handles")
