3par drivers terminate connection requires host validation

[Kurt Martin]

The 3PAR backend does not allow FQDN host names (i.e. foo.rose.hp.com), it requires just foo without the rose.hp.com. The 3PAR driver are checking the host name in the initialize connection but not in the terminate connection. This is causing the following exception:

 HTTPNotFound: Not found (HTTP 404) 17 - host does not exist

    3PAR driver terminate connection host validation

    The 3PAR backend does not allow FQDN host names (i.e. foo.rose.hp.com),
    instead it requires just foo without the rose.hp.com. This patch will
    now validate the host name in terminate connection by calling
    _safe_host just as it was doing in initialize connection when creating
    the host on the 3PAR backend.
