add rewind-safeguard parameter

Rewinding the ring buffer completely causes audible issues with DMAs.
Previous solution didn't work with tsched=0, and used tsched_watermark
for guardband, which isn't linked to hardware and could become really high
if underflows occurred.

Added separate parameter that can be tuned to hardware limitations and size
of DMA bursts.
