ALSA: jack: Access input_dev under mutex
[ Upstream commit 1b6a6fc5280e97559287b61eade2d4b363e836f2 ]
It is possible when using ASoC that input_dev is unregistered while
calling snd_jack_report, which causes NULL pointer dereference.
In order to prevent this serialize access to input_dev using mutex lock.
