Subject: [PATCH] drm/qxl: remove unnecessary BUG_ON check for handle

In qxl_gem_object_create_with_handle(), handle's memory is not
allocated on the heap. Checking for failure of handle via BUG_ON
is unnecessary. This patch eliminates the check.

The check makes sure the caller doesn't pass in handle == NULL
and it is needed.
