drm: Make control nodes master-less v3
Like for render-nodes, there is no point in maintaining the master concept for control nodes, so set the struct drm_file::master pointer to NULL. At the same time, make sure DRM_MASTER | DRM_CONTROL_ALLOW ioctls are always allowed when called through the control node. Previously the caller also needed to be master. v2: Adapt to refactoring of ioctl permission check. v3: Formatting of logical expression. Use drm_is_control_client() instead of drm_is_control().
