Revert "xwm: Fix memory leak"

This reverts commit d2cb711d81.

I missed the call to cairo_image_surface_create_for_data() which assumes
the data will remain present until the cairo surface is destroyed. It
seems the existence of data depends on the reply not being freed.

This will need a more involved fix.

Sorry, I noticed this just seconds after I pushed the patch.
