[PORT FROM R2]audio: sn95029: Fix headset detect issue in a calling

BZ: 16131

Case1: cancel_delayed_work in sn95031_jack_wq will casue some useful work
removed when insert headset,it will lose the last headset status update and
report to headsetObserver sometimes.

Case2: Clear the jack_wq->intr_id flag also will cause headset detect error,
when jack detect wq running,the last interrupt occur and schedule the work
queue, then jack_wq->intr_id was cleared by current wq,after 250ms passed,
the wq will first check the jack_wq->intr_id=0, then report headset remove
event to user space.

Fix Case1&Case2 issues.
