[PATCH 03/20] fbconsole: fix handling of CSI buffer overflow

[Ahmad Fatoum]

To avoid overflowing the CSI buffer, a check for csipos == 255
aborts the CSI parse and reverts to expecting literal characters.

This is fine, but afterwards the if clause terminates with a return
instead of a break which results in priv->in_console never being reset.

Use break, so the relevant code after the switch is not skipped.
