Don't answer to BSC-originated RESET with another RESET
If the BSC is contacting us for the first time and sending a BSSMAP
RESET, then we should simply ACK that and transition into the
"connected" state, where connection-oriented and connectionless
procedures are permitted.
This patch is a bit large for such a seemingly simple behavioural
change, but the existing data model didn't permit a more
straight-forward implementation.
