drm/i915: Replace struct_mutex in intel_guc_log
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.
