When SC fail-overs, the new AMFD active will send
AVSV_D2N_DATA_VERIFY_MSG message event to AMFND.
When AMFND processes this event, it also send the
protection group (PG) start message to new active
AMFD. In case MDS has not updated its tables by
this time, then AMFND still send to old active AMFD.
Solution in this case is to force AMFND send to
specified AMFD.

With this funtion we are sending msg to the new active AvD
