[PATCH] dix: ignore devices when adding passive core grabs to list (#39545)

[Peter Hutterer]

Passive core grabs are mostly device-independent. In an MPX scenario, they
may change to reflect whichever master pair activated the grab last. For
adding new grabs to the list, ignore the device for core grabs to return
failures when trying to set the same grab combo twice on a window.
