HFP: notify HF about call status forcibly

When call is hung up and still there is another
call is in active,some of the HF cannot acquire
the call states by its own. If HF try to terminate
a call, it may not send the command AT+CHUP because
the call states are not updated properly. HF should
get informed the call status forcibly.
