    net/iavf: fix taninted scalar
    
    tainted_data_downcast: Downcasting match_item->meta from void * to
    struct virtchnl_proto_hdrs implies that the data that this pointer points
    to is tainted.
    
    var_assign_var: Assigning: proto_hdrs = match_item->meta.
    Both are now tainted.
    
    var_assign_var: Assigning: rss_meta->proto_hdrs = *proto_hdrs. Both are
    now tainted.
    
    Passing tainted expression "rss_meta->proto_hdrs.count" to
    "iavf_refine_proto_hdrs", which uses it as a loop boundary.
    
    Removed temporary variable 'proto_hdrs', and copied whole memory of
    match_item meta with exact structure size to avoid data downcast.
    
    Coverity issue: 381131
    
    Fixes: 91f27b2e39ab ("net/iavf: refactor RSS")
