[PATCH v5 17/21] libmultipath: pathinfo: don't blank wwid if checker fails

[Martin Wilck <mwilck@suse.com>]

Blanking a WWID is a dangerous operation. E.g. configure() would
consider the path in question as invalid and orphan it if the
WWID is blank. Don't do this checker failures which may be transient
or indicate a badly configured or otherwise malfunctioning checker.
Moreover, we try to determine WWID even if path_offline returns
PATH_DOWN in the first place, so why should we not if the checker
has a problem?
