By using strncasecmp, we allow for arbitrary characters after the
"on"/"off" string. Fix this by switching to strcasecmp.

FWIW the ordering is wrong here. The tags are supposed to document the
patch flow: The patch was first signed off by the author (Jan), then
reviewed, then signed off by committers. Not first reviewed.

No need to respin but please keep in mind for the future.
(Yeah, did that wrong myself before.)
