multipathd: print path offline message even without a checker

If a path has a checker selected and is offline, multipathd will print a
"path offline" message. However if the checker isn't selected, for
instance because multipathd was started or reconfigured while the path
was offline, multipathd was not printing the "path offline" message.
Fix that.
