audio: hal: Fix for non dolby clip playback issue

-Non dolby clip followed by dolby clips are not playing as
 ip handler is getting initialized two times, first in
 audio_extn_qaf_init and second in adev_open_output_stream.
 Ip handler init from adev_open_output_stream should not be called
 from adev_open_output_stream for MS12 decode.

-Fix this by avoiding ip handler init from adev_open_output_stream
 if qaf enabled.
