SSC volume filtering for extra specs can result in inconsistent list

[Navneet]

The volume filtering to match volume type extra specs operates on the original data structure. This can cause inconsistency on the original list of netapp volumes available during certain operations. The better method would be to operate on the copy of data structure and not the original list hence keeping the original volumes safe for future provisioing operations.

    NetApp fix ssc volume filtering inconsistency

    This fixes the situation when the actual netapp
    volume data structure becomes inconsistent
    because of operating on the actual object
    than the copy of it. It also introduces some checks
    before calculating volume stats.
