Stepan Ionichev b400c076fe counter: ftm-quaddec: use devm_mutex_init()
ftm_quaddec_probe() calls mutex_init() but neither the cleanup
action nor a remove callback issues a matching mutex_destroy(),
so the lock debug state is leaked on driver unbind.

Switch to devm_mutex_init() so the mutex is torn down in the same
devm scope it was set up in.
