Keydisabler: fix button light restore logic

Do not assign default button brightness if backup key is not found.
Instead do nothing. This will prevent brightness being reset to default
on boot when navbar is disabled.

If backup key is not found when actually toggling navbar then we've got
bigger problems.

In change 46af8086db0db5b41f20c9f05a5f42c182262576 the option
to enable/disable the wireless display was moved to an action
bar which ends up entirely removing the ability to enable it
for devices using Settings in tablet (multi-pane) mode.

Follow the pattern of dreamcast which correctly displays
and removes the action bar.

On tall displays this ends up with a lot of useless padding
in the list.
