loop: Push lo_ctl_mutex down into individual ioctls
Push acquisition of lo_ctl_mutex down into individual ioctl handling branches. This is a preparatory step for pushing the lock down into individual ioctl handling functions so that they can release the lock as they need it. We also factor out some simple ioctl handlers that will not need any special handling to reduce unnecessary code duplication.
