Olivier Fourdan a49e7b9c2e xwayland: fix a crash on output removal
On output removal, the CRTC that was added in xwl_output_create()
is not removed in xwl_output_destroy() and would cause a segmentation
fault later on in ProcRRGetMonitors():

  (EE) Segmentation fault at address 0x100000001

Remove the output CRTC in xwl_output_destroy() to avoid the crash.
