Xi: allow for XIAllowEvent requests larger than XI < 2.2 size (#68554)

Browse Source 
XIAllowEvents changed length in XI 2.2 (for the touchid). A bug in libXi
causes libXi to always use the new request length if the server supports
2.2, regardless of the client's XIQueryVersion request.

The server takes the client's XIQueryVersion request into account though,
resulting in a BadLength error if a 2.[0,1] client calls XIAllowEvents on a
XI 2.2+ server.

Can't fix this in libXi, so work around this in the server.
