Bug Description

The Storwize driver mistakenly checks on startup if vdisk_count > 0 for io groups, and fails if this is not the case. This means that controllers with empty io groups cannot be used.

    Storwize: Fix iogrp availability check

    Do not check if vdisk_count is greater than zero to determine iogrp
    availability. This is wrong, and leads to the driver not being able to
    use empty iogrps.
