Fix xwayland related crash when mousing out of a window

XWayland likes to set a buffer on the cursor surface then delete it before
we release it.  I'm pretty sure when a client does that we're within spec
to just kill it, but users will likely find this response ungratifying.

So, instead, just gracefully fail to render the undefined surface.
