This patch is a follow up to commit 4cf3fd4 "add support for indicating
the boot state using three leds".
At the time of writing the patch, I wasn't aware that it's possible to
switch info failsafe after boot (factory reset).
Enabling the failsafe led without disabling the running led causes an
unexpected led colour on devices using a single multicolour led to
indicate the boot state.
