trxcon: trx_if_close(): power the transceiver off if needed 

Currently it may happen that the transceiver (e.g. fake_trx.py) remains
powered on when we loose a L1CTL client connection.  This is going to
be fixed in change [1] re-implementing the trxcon_fsm.  For now let's
ensure that the transceiver is properly powered off by sending
"CMD POWEROFF" from trx_if_close().
