Remove the use of struct_mutex from intel_guc_log.c and replace it with a dedicated lock, guc_lock, defined within the intel_guc_log struct. The struct_mutex was previously used to protect concurrent access and modification of intel_guc_log->level in intel_guc_log_set_level(). However, it was suggested that the lock should reside within the intel_guc_log struct itself. Initialize the new guc_lock in intel_guc_log_init_early(), alongside the existing relay.lock. The lock is initialized using drmm_mutex_init(), which also ensures it is properly destroyed when the driver is unloaded.
