Subject: [PATCH] multipath: deal with delegation failures correctly
delegate_to_multipathd() was returning success, even if the multipathd
command failed. Also, if the command was set to fail with NOT_DELEGATED,
it shouldn't print any errors, since multipath will try to issue to
command itself.
Fixes: "multipath: delegate flushing maps to multipathd"
