    xenapi: Fix when auto block_migration in the API
    
    When nova calculates live migration type it stores the calculated
    type in migrate_data.block_migration. Because of that we really should
    not use block_migration, because it might not be accurate in certain
    cases.

Title:
  Xenapi live-migration does not work at all now

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  In case Nova calculated live migration type by itself and it's a block
  live migration, it will not work if Xen is used because of invalid
  check in driver:

  https://github.com/openstack/nova/blob/dae13c5153a3aee25c8ded1cb154cc56a04cd7a2/nova/virt/xenapi/vmops.py#L2391

  Basically because here block_migration will be None and real value
  will be stored in migrate_data.block_migration
