Title:
  NSX: wrong switch uuid reference used during dhcp/metadata operations

Status in OpenStack Neutron (virtual network service):
  Fix Released
Status in neutron icehouse series:
  New

Bug description:
  Change https://review.openstack.org/#/c/54578/ introduced a DB mapping
  between neutron network uuids and NSX logical switch uuids.

  Some parts of the NSX plugin have not been fully updated to reflect
  the new logic and this result in stacktraces like these:
