ASoC: nau8821: Cancel pending work before suspend

Browse Source 
[ Upstream commit 7786b10688 ]

A jack detection work that is unscheduled or in progress while executing
the suspend handler could trigger a race condition.

Ensure state consistency by cancelling any pending work or wait for its
execution to complete before processing the suspend.  Since driver
(re)enables both insert and eject interrupts on resume, there is no risk
to miss the related jack events.  Therefore, flush_delayed_work() is not
required here.
