ALSA: scarlett2: Fix scarlett2_*_ctl_put() return values again
Mixer control put callbacks should return 1 if the value is changed.
Fix the mute, air, phantom, direct monitor, speaker switch, talkback,
and MSD controls accordingly.
Fix scarlett2_speaker_switch_enable() to not ignore the return value
of scarlett2_sw_hw_change().
