Title:
  Compute leaks volume attachments if we fail in
  driver.pre_live_migration

Status in OpenStack Compute (nova):
  Fix Released
Status in OpenStack Compute (nova) queens series:
  Confirmed
Status in OpenStack Compute (nova) rocky series:
  Confirmed

Bug description:
  ComputeManager.pre_live_migration fails to clean up volume attachments
  if the call to driver.pre_live_migration() fails. There's a try block
  in there to clean up attachments, but its scope isn't large enough.
  The result is a volume in a perpetual attaching state.
