ASoC: qdsp6: q6routing: Conditionally reset FrontEnd Mixer
Stream IDs are reused across multiple BackEnd mixers, do not reset the
stream mixers if they are not already set for that particular FrontEnd.
Ex:
amixer cset iface=MIXER,name='SLIMBUS_0_RX Audio Mixer MultiMedia1' 1
would set the MultiMedia1 steam for SLIMBUS_0_RX, however doing below
command will reset previously setup MultiMedia1 stream, because both of them
are using MultiMedia1 PCM stream.
amixer cset iface=MIXER,name='SLIMBUS_2_RX Audio Mixer MultiMedia1' 0
reset the FrontEnd Mixers conditionally to fix this issue.
This is more noticeable in desktop setup, where in alsactl tries to restore
the alsa state and overwriting the previous mixer settings.
