backend-drm: set DRM_MODE_ATOMIC_ALLOW_MODESET during head disable

Browse source 
A change in the connector state require a possible full modest depending on the
hardware.

The connector wasn't set to unconnect if the head was detached while the output
is still enabled. Fix this by always checking the disable_head_link list during
drm_output_apply_state_atomic().
