Add force parameter to client restore and pass value through the layers. The only currently used value is false. If force is true, the client should restore its display even if it does not hold the DRM master lock. This is be required for emergency output, such as sysrq. While at it, inline drm_fb_helper_lastclose(), which is a trivial wrapper around drm_fb_helper_restore_fbdev_mode_unlocked().
