audio: Fixed Audio Source in Voice Call

setPhoneState calls getDeviceForInputSource to check if
voice_tx device is available as part of Primary Audio
Module. getDeviceForInputSource always returns
DEVICE_IN_COMMUNICATION for SOURCE_VOICE_COMMUNICATION
on A Family and this is not added to Available devices
This is leading to creation of txPatch when it is not
needed

Fix is to use AUDIO_SOURCE_VOICE_CALL instead of
AUDIO_SOURCE_VOICE_COMMUNICATION this fix is present
in I9aa7dd2139b8374ec7f06676d06ef5addea4b2a9 and
removed during MR1 upgrade
