Use look up service for auto zoning

Use look up service for auto zoning

The VMAX FC driver didn't use the look up service for auto zoning.
Instead it built initiator target map itself. However, that
requires the initiator to log into the fabric before zoning
in order to find out target WWNs.

This patch is to use the look up service to find out valid initiator
target WWNS and use that to build initiator target map. With this fix,
the initiator is no longer required to log into the fabric ahead of time.
