hwmon: (nzxt-smart2) handle failure of devm_add_action in nzxt_smart2_hid_probe
1. replace the devm_add_action with devm_add_action_or_reset to ensure
the mutex lock can be destroyed when it fails.
2. use local wrapper function mutex_fini instead of mutex_destroy to
avoid undefined behaviours.
3. add a check of devm_add_action_or_reset and return early when it fails.
