    EMC VNX: Fix the total capacity for dynamic Pool

    For the pools that are not dynamic, the total capacity of the pool returns
    as total size of all members of the pool; For the pools that are dynamic,
    it returns the potential, maximum total size, in other words the total size
    of all members plus the space available for the pool extension.
