[Qemu-devel] [PATCH] ui/input: correct the release order of combined keys

[Amos Kong <akong@redhat.com>]

Commit 2e377f17 wrongly overturned the release order of combined keys,
it caused some Windows guests can't be paniced by "virsh send-key
<domain> KEY_RIGHTCTRL KEY_SCROLLLOCK KEY_SCROLLLOCK"

The press event order should be different with release order.
