ozone: evdev: Fix repeating the same key after r324081

We broke repeating the same key twice in a row in r324081. Cancelling
repeat must update the repeated key, so that we can tell that we need
to start a new repeat for that key in UpdateKeyRepeat if it's pressed
again.

TEST=Repeat the same key twice in a row on link
