ASoC: Intel: avs: Set of functional fixes

Merge series from Cezary Rojewski <cezary.rojewski@intel.com>:

Medium range of fixes all avs-driver related. The most important fixes
lead the way:

1. For ASoC-hda codec driver, existing RPM manipulation in
hda_codec_probe_complete()'s error path is superfluous and leads to RPM
usage count underflow if the probe exists early e.g.: build-controls
operation fails.

2. Resolve deadlock when DSP-recovery is a consequence of SET_D0IX IPC.
The procedure handling IPC timeouts and EXCEPTION_CAUGHT notification
shall cancel any D0IX work before proceeding with DSP recovery. If
SET_D0IX called from delayed_work is the failing IPC the procedure will
deadlock.

3. LINK format (PPLCxFMT) calculation is incorrect.
HDAudio transfer types utilize SDxFMT for front-end (HOST) and PPLCxFMT
for back-end (LINK) side when setting up the stream. BE's
substream->runtime duplicates FE runtime so switch to using BE's
hw_params to address incorrect format values on the LINK side when FE
and BE formats differ.

Below three patches address problems found by Coverity static analyzer:
  ASoC: Intel: avs: Fix possible null-ptr-deref when initing hw
  ASoC: Intel: avs: Verify kcalloc() status when setting constraints
  ASoC: Intel: avs: Verify content returned by parse_int_array()

While unlikely in runtime, it's good to keep code resilient. The last
few patches are readability/cohesiveness improvements.
