    libpcp pmns - fix obscure memory leak

    To see this you'd need to be using PM_CONTEXT_LOCAL for a DSO
    PMDA with dynamic metrics and then call pmGetChildren() or
    pmGetChildrenStatus() and the metric at the root of the search
    needs to be a non-leaf with more than zero children.

    This corner case is exposed by qa/957.
