Subject: [PATCH 21/21] Fix NULL pointer passed to wl_event_queue_destroy

In eplWlDisplayInstanceCreate, the queue variable may remain NULL if an
error occurs before an event queue is successfully created. The cleanup
code at the done label would then pass NULL to wl_event_queue_destroy,
which does not safely handle NULL pointers.

Add a NULL check before calling wl_event_queue_destroy to prevent this.
