ASoC: nau8821: Fixup nau8821_enable_jack_detect()

The nau8821_enable_jack_detect() function was supposed to allow enabling
or disabling jack events reporting.  However, once enabled, any
subsequent invocation would fail and the following splat is shown:

Introduce jdet_active flag to driver data structure and use it to
provide one-time initialization of the jack detection work queue and
related interrupt line.

Note this is also a prerequisite for additional fixes around module
unloading and suspend handling.
