[wayland] avoid potential crash when checking for window inhibitions on desktop change

Browse source 
Summary:
Xwayland clients are sometimes offset from being visible to having a
surface applied.

We might also have internal windows which will be AbstractClients
without a surface.

No idle interface will be set up for non wayland clients, but on a
desktop change we itterate through all AbstractClients and need to guard
somewhere.

BUG: 420039

Test Plan: None
