ALSA/dummy: Replace tasklet with softirq hrtimer
The tasklet is used to defer the execution of snd_pcm_period_elapsed() to
the softirq context. Using the HRTIMER_MODE_SOFT mode invokes the timer
callback in softirq context as well which renders the tasklet useless.
[o-takashi: avoid stall due to a call of hrtimer_cancel() on a callback of hrtimer]
