compositor-drm: Delete drm_backend_set_modes
we stopped forcing a modeset when restoring the session. The motivation
was that we would use a stale fb, so better to let the next repaint
handle it.
However, if drm_output::fb_current != NULL, we won't issue a modeset
upon repaint.
This change unreferences both drm_output::fb_current and
drm_output::fb_pending when deactivating the current session. This
ensures the very first repaint after restoring the session will issue a
modeset.
