ASoC: rt5645: Fix deadlock in rt5645_jack_detect_work()

Browse source

There is a path in rt5645_jack_detect_work(), where rt5645->jd_mutex
is left locked forever. That may lead to deadlock
when rt5645_jack_detect_work() is called for the second time.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
