ASoC: wm8994: Prevent double lock of accdet_lock mutex on wm1811

commit b38314179c upstream.

wm1811_micd_stop takes the accdet_lock mutex, and is called from two
places, one of which is already holding the accdet_lock. This obviously
causes a lock up.

This patch fixes this issue by removing the lock from wm1811_micd_stop
and ensuring that it is always locked externally.
