Bug description:
  SUMMARY:
  Wrong path used when detecting multipath id

  ANALYSE:
  when multipath device path was not found via LUN wwn, os-brick would use device path like below:

  /dev/disk/by-path/ip-192.168.3.52:3260-iscsi-
  iqn.1992-04.com.emc:cx.apm00153906536.b5-lun-155

  to detect multipath id via 'multipath -l <device path>'

  but this cause error:
  : can't get udev device

  actually, we should use its real path like /dev/sdb, dev/sda to detect
  the multipath id.
