MFC r325355:
  Use correct pointer in key_updateaddresses() when updating NAT-T config.

  key_updateaddresses() is used to update SA addresses and NAT-T
  configuration in SADB_UPDATE message. This is done using cloning SA
  content from old SA into new one. But addresses and NAT-T configuration
  are taking from SADB_UPDATE message. Use newsa pointer to set NAT-T
  properties into cloned SA.
