rds: Fix regression in dynamic active bonding configuration

OraBug: 18481645

Commit 6cf7cc30 "rds: dynamic active bonding configuration" introduced
a regression. Late joining IB interfaces were not configured
correctly.  When active bonding configuration shows both interfaces
down, IP failover was not happening.  This patch fixes this issue.
