ASoC: nau8821: Avoid unnecessary blocking in IRQ handler

The interrupt handler offloads the microphone detection logic to
nau8821_jdet_work(), which implies a sleep operation.  However, before
being able to process any subsequent hotplug event, the interrupt
handler needs to wait for any prior scheduled work to complete.

Move the sleep out of jdet_work by converting it to a delayed work.
This eliminates the undesired blocking in the interrupt handler when
attempting to cancel a recently scheduled work item and should help
reducing transient input reports that might confuse user-space.
