ASoC: rt5682: Fix panic in rt5682_jack_detect_handler happening during system shutdown

During Coldboot stress tests, system encountered the following panic.
Panic logs depicts rt5682_i2c_shutdown() happened first and then later
jack detect handler workqueue function triggered.
This situation causes panic as rt5682_i2c_shutdown() resets codec.
Fix this panic by cancelling all jack detection delayed work.
