xwayland: fix CVE-2025-62229

A flaw was found in the X.Org X server and Xwayland when processing
X11 Present extension notifications. Improper error handling during
notification creation can leave dangling pointers that lead to a
use-after-free condition. This can cause memory corruption or a crash,
potentially allowing an attacker to execute arbitrary code or cause a
denial of service.
