HP 3PAR FC driver should support adding WWNs to hosts

[Jim Branen]

If the FC driver has an existing 3PAR host with FCPaths already configured, the driver will not add any more WWNs to it. The driver should be enhanced to add a WWNs that does not already exist for a given host.

    3PAR FC: add ability to add WWNs to host

    When a host is created on the HP 3PAR array,
    at initialize connection time, the host is
    created with all WWNs provided in the connector
    structure. However, the driver did not have
    the ability to add new WWNs after a host is created.

    This patch adds the ability to add WWNs to a
    host, at initialize connection time, if a new
    WWN is provided in the connector structure.
