Title:
  multipath device action incorrectly being parsed as the device name

Status in OpenStack Compute (nova):
  In Progress
Status in os-brick:
  Fix Released

Bug description:
  multipath device action incorrectly being parsed as the device name.

  The first word on the first line of `multipath -l $path` is currently
  being used as the name of a given multipath device.

  https://github.com/openstack/nova/blob/master/nova/storage/linuxscsi.py#L118
  https://github.com/openstack/os-brick/blob/master/os_brick/initiator/linuxscsi.py#L145

  This however can be an `action:` string when the device is being
  created,  reloaded, resized etc. [1][2][3]
