multipath -l <device_name> is failing

[Rajat Dhasmana]

While creating instance from bootable volume, during attaching the volume, after the export and map, we try to find multipath for the discovered device.

when we don't find any multipath device in the following paths:

1) /dev/disk/by-id/dm-uuid-mpath-<WWID>
2) /dev/mapper/<WWID>

we try to execute ``multipath -l <device_name>`` which fails
