xi2: Reset scroll valuators on synthesized crossing events

Browse Source 
On crossing events resulting from moving windows (eg. workspace switch),
deviceid equals sourceid, so make those reset scroll valuators on all
slave devices to avoid misleading jumps in scroll events

Fixes https://bugzilla.gnome.org/show_bug.cgi?id=690275
