Subject: xfree86: Take the input lock for xf86RecolorCursor
xf86RecolorCursor() may be called directly from XRecolorCursor as well
as from xf86ScreenSetCursor(). In the latter case, the input lock is
already held, but not for the former and so we need to add a wrapper
function that acquires the input lock before performing
xf86RecolorCursor()
