ASoC: SOF: ipc4-pcm: reset skip_during_fe_trigger pipelines before DE…

Bug: SOF IPC4 compressed audio fails on second playback (WCL/PTL/SoundWire)

Component: Sound / SOF IPC4 driver
Platform: Intel WCL/PTL with RT721-SDW codec
Symptom: First AAC compressed playback succeeds; every subsequent attempt fails immediately with ERR: cannot set device: Invalid argument.

Root cause:
Shared output pipelines marked skip_during_fe_trigger=1 bypass started_count/paused_count updates during the STOP trigger. At teardown, SET_PIPELINE_STATE(RESET) is never issued for these pipelines because the condition !started_count && !paused_count evaluates to false. When DELETE_PIPELINE is sent while the pipeline is still in RUNNING state the firmware rejects it with error 12 ("Required resource is in invalid state"). The pipeline remains stranded in firmware, so the next CREATE_PIPELINE for that pipeline instance fails with error 9, blocking all further compressed stream opens.
LOG:
