xkb: Don't swap XkbSetGeometry data in the input buffer
The XkbSetGeometry request embeds data which needs to be swapped when the
server and the client have different endianess.
_XkbSetGeometry() invokes functions that swap these data directly in the
input buffer.
However, ProcXkbSetGeometry() may call _XkbSetGeometry() more than once
(if there is more than one keyboard), thus causing on swapped clients the
same data to be swapped twice in memory, further causing a server crash
because the strings lengths on the second time are way off bounds.
To allow _XkbSetGeometry() to run reliably more than once with swapped
clients, do not swap the data in the buffer, use variables instead.
