[regression] daily stable v2.2 shows regression across multiple boards

[ujfalusi]

There is a clear regression happened after merging #5262
49350 test run is clean, before merging it
49411 failures across multiple boards

The changes between the two tests in kernel:

e2b6395070e8 ASoC: SOF: ipc4-topology: Remove the skip_during_fe_trigger flag
45e374d0e139 ASoC: SOF: Refactor pipeline management
9232c227d9ab drivers: soundwire: Add new prepare op in struct sdw_intel_ops
962f8bbd7468 ASoC: SOF: sof-audio: Add helper functions for BE managed pipelines
f14ac2b9dc4f ASoC: SOF: pcm: Split up widget prepare and setup
259fa001dbaa ASoC: SOF: sof-audio: Add a new op in struct sof_ipc_tplg_ops

The PR test for stable v2.2 was clean.

@ranj063, @kv2019i, @bardliao, if we cannot fix this fast we should revert #5262 and rework it.

It looks like that the use_count for widgets are incrementing.
