xwayland.c handle_map(): NULL out xsurface->data() to prevent crashing.
When changing a surface from managed to unmanaged in handle_map(), the
call to handle_destroy(.., view) causes the sway_xwayland_view pointed
to by the untyped wlr_xwayland_surface.data field to become invalid
garbage, yet the untyped wlr_xwayland_surface.data continues to point
at it. In particular: view_get_*(view_from_wlr_surface(..)), even
with appropriate NULL checking, will crash sway when this codepath is
exercised (reliable test case: drop-down menus in Google Earth).
