drm-backend: fix deinit_planes

Browse source 
Commit "drm-backend: move code to init/deinit planes to specific
functions" lost a chunk of drm_output_deinit() when moving code into
drm_output_deinit_planes(). Reinstate the missing chunk.

This fixes an endless loop over weston_compositor::plane_list when you
start with three monitors connected, unplug and re-plug one.

Fixes: 3be23eff99
