plugins: simlpify gst_vaapi_create_display() helper.

Simplify gst_vaapi_create_display() helper as gst_vaapi_display_XXX_new()
performs the necessary validation checks for the underlying VA display
prior to returning to the caller. So, if an error occurred, then NULL is
really returned in that case.
