ASoC: rt711-sdca-sdw: fix calibrate mutex initialization
In codec driver bind/unbind test, the following warning is thrown: DEBUG_LOCKS_WARN_ON(lock->magic != lock) ... [ 699.182495] rt711_sdca_jack_init+0x1b/0x1d0 [snd_soc_rt711_sdca] [ 699.182498] rt711_sdca_set_jack_detect+0x3b/0x90 [snd_soc_rt711_sdca] [ 699.182500] snd_soc_component_set_jack+0x24/0x50 [snd_soc_core] A quick check in the code shows that the 'calibrate_mutex' used by this driver are not initialized at probe time. Moving the initialization to the probe removes the issue.
