BS-11: Send proprietary MRPCI message after assignment has completed

This is a non-standard RSL message that must be sent after each traffic
channel has been established.  Without it, any voice call will be
disconnected within seconds.

This is a hack; we need to store the subscribers classmark2 value and
use it here.
