xwayland: fix CVE-2025-62230

A flaw was discovered in the X.Org X serverâ\x80\x99s X Keyboard
(Xkb) extension when handling client resource cleanup. The software
frees certain data structures without properly detaching related
resources, leading to a use-after-free condition. This can cause
memory corruption or a crash when affected clients disconnect.
