xkb: fix turbo-repeat of RedirectKey-ed keysyms

RedirectKey() action had been broken by commit 2e6190.
A dropped check caused over-intense autorepeat of keysyms enriched
with the action.

Previous to this commit, the check wrapped the entire switch() block,
which was dropped with the move to a separate function.

Restore the checking.
