Input: fix stale timestamp on key autorepeat events

We need to refresh timestamp when emitting key autorepeat events, otherwise
they will carry timestamp of the original key press event.

Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=206929
Fixes: 3b51c44b ("Input: allow drivers specify timestamp for input events")
