[dm-devel] [PATCH 2/2] multipathd: Don't call repair on blacklisted paths

[Mike Christie]

This fixes a regression added in
015f87b16a7797a17afd514aec46e65c2a1a2f73

If a path is blacklisted the checkerloop will free the path so
don't call repair on it.

This moves the repair call down into check_path, because I think
we also do not need to call it for other cases where we cannot get
the uuid info or being orphaned.
