[PATCH libXi] Don't overwrite the cookies serial number

[Peter Hutterer]

serial != sequenceNumber, see _XSetLastRequestRead()

cookie->serial is already set at this point, setting it again directly from
the sequenceNumber of the event causes a bunch of weird issues such as
scrollbars and text drag-n-drop breaking.

Fixes regression introduced in 5d43d4914dcabb6de69859567061e99300e56ef4
