amf: fix mismatch message id during sc fail-over [#3342]
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.

Some information
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 can not send to AMFD.
Solution in this case is to force AMFND send to specified AMFD.
