a_iface_bssap: Treat inbound RESET as implicit RESET ACK

If both sides are sending RESET at the same time, they are not aware
of each other.  This leads to synchronization problems in wich
the remote side is transmitting e.g. a COMPL L3 INFO after receiving
a RESET ACK, but before even receiving or processing the RESET in
the inverse direction.  So let's treat receiving a RESET as an implicit
RESET ACK to any RESET we may have sent.
