ALSA: hrtimer: remove superfluous tasklet invocation
Commit bb758e9637e5ddc removed snd_hrtimer_callback() from the hardware interrupt handler, thus moving it into a tasklet, but did not tell the ALSA timer framework about this, so the timer handling would now be done in the ALSA timer tasklet scheduled from another tasklet. To fix this, add the flag to tell the ALSA timer framework that the timer handler is already being invoked in a tasklet.
