comctl32/updown: Don't pass VK_[UP|DOWN] to original Up/Don control buddy's winproc

[Nikolay Sivov]

http://bugs.winehq.org/show_bug.cgi?id=7033

When you press up/down keys caretr should be set to leftmost position
of updown control buddy edit control if a value changed.
If value didn't change caret shouldn't change position.
Mouse wheel isn't affected here cause buddy defproc handle it the way we want
for up/down.

Changelog:
    - Don't pass VK_[UP|DOWN] to original Up/Don control buddy's winproc
