cifs: add lease tracking to the cached root fid
Use a read lease for the cached root fid so that we can detect when the content of the directory changes (via a break) at which time we close the handle. On next access to the root the handle will be reopened and cached again. Signed-off-by: Ronnie Sahlberg <lsahlber@redhat.com> Signed-off-by: Steve French <stfrench@microsoft.com>
