Peter Hutterer 9d6b836570 dix: fix crash on XI 1.x grabs on disabled devices. (#54934) 
If the device is disabled, the sprite window is NULL and dereferencing
crashes the server.

This is only triggered for XI 1.x grabs (ProcXGrabDevice) as XI2 grabs would
trigger another code path, creating a sprite for the disabled device as if
detaching it (which is wrong and fixed with this patch too).

Grabbing a disabled device doesn't make sense as it won't send events
anyway. However, the protocol specs do not prohibit it, so we need to keep
it working.
Luckily, oldWin is only used for focus out events, which aren't necessary
given that the device is disabled.
