TWSP-HFP: perform post sco close action after sco close during codec negotiation

In some corner case, end call happened during codec negotiation, so will call
close sco first, then send indicator values. But BTA AG SCO is in CODEC_ST
state, close sco just move SCO SM state from CODEC_ST to LISTEN_ST, end call
indicator will no chance to send in this situation.
