vdev_id: fix failure due to multipath -l bug
Udev may fail to create the expected symbolic links in
/dev/disk/by-vdev on systems with the
device-mapper-multipath-0.4.9-100.el6 package installed. This affects
RHEL 6.9 and possibly other downstream distributions.
That version of the multipath command may incorrectly list a drive
state as "unkown" instead of "running". The issue was introduced
in the patch for https://bugzilla.redhat.com/show_bug.cgi?id=1401769
The vdev_id udev helper uses the state reported by "multipath -l" to
detect an online component disk of a multipath device in order to
resolve its physical slot and enclosure. Changing the command
invocation to "multipath -ll" works around the above issue by causing
multipath to consult additional sources of information to determine
the drive state.
