    Fix bug with 3PAR host entry in wrong domain

    This patch exposes a more acurate exception message
    when a user has created a manual host entry on a
    3PAR system that is in an incorrect 3PAR domain than
    the domain that is configured for the 3PAR driver.

    The bug complained that it couldn't find a VLUN, when the
    actual problem was the host existed in the wrong 3PAR domain.

    Fixes bug #1158991
