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.
