cfm: Implement 802.1ag RDI flag.

According to the 802.1ag specification, a maintenance point should
set the Remote Defect Indicator (RDI) bit on CCMs when it has
failed to receive a CCM from any of it's configured remote
maintenance points within the required fault interval.  This allows
unidirectional faults to be flagged by both ends of a CFM monitored
tunnel.
