ALSA: PCM - Don't check DMA time-out too shortly

When the PCM period size is set larger than 10 seconds, currently the
PCM core may abort the operation with DMA-error due to the fixed timeout
for 10 seconds.  A similar problem is seen in the drain operation that
has a fixed timeout of 10 seconds, too.

This patch fixes the timeout length depending on the period size and
rate, also including the consideration of no_period_wakeup flag.
