dsp: return ENETRESET error if apr is down

Browse Source 
In SSR/PDR, return ENETRESET errno to
propagate this failure to userspace. After
audio HAL receives ENETRESET, it stops retry
for pcm_open continuously. Rate limit the logs
when apr send packet fails during PDR/SSR
usecases to avoid watchdog timeouts.
