alsa_sound: Add missing assignment of acdb_handle, fixes in-call volume

Assigns AudioHardwareALSA::mUcMgr->acdb_handle to mAcdbHandle, which is
missing in the port of dynamic library loading from the AOSP/mako HAL
(I04d5e7b96611572a7758c610ebdf0fd00e8346aa).

Restores acdb_send_voice_cal and acdb_send_audio_cal calls, which among
other things, are required for in-call volume adjustment to function.
alsa_sound: Force calling of setVoiceVolume at the start of every call.

Fixes the problem whereby some call start at max volume regardless of the
in-call volume setting.
