ALSA: control: Use deferred fasync helper
For avoiding the potential deadlock via kill_fasync() call, use the
new fasync helpers to defer the invocation from the control API. Note
that it's merely a workaround.
Another note: although we haven't received reports about the deadlock
with the control API, the deadlock is still potentially possible, and
it's better to align the behavior with other core APIs (PCM and
timer); so let's move altogether.
