    linux pmda - fix missing initialization for netstat metrics
    
    Found by qa/003 on ia64 grundy.sgi.com SUSE SLES11 SP1.
    
    We must have been simply lucky on other platforms, as this had the
    potential to whack data in the linux PMDA's address space, and hence
    pmcd (the linux PMDA is a DSO agent by default).

    qa/valgrind-suppress-3.8.1 - similar to 3.6.1 case
    
    Bogus uninitialized data in jump report ... seems to be i?86 specific
    as well as valgrind version dependent.
