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

[Armando Migliaccio]

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:

    NSX: add nsx switch lookup to dhcp and metadata operations

    The operations in questions were still using the neutron network
    uuid as the nsx switch uuid, but this is no longer valid.

    Close-bug: #1312439
