Eric Dumazet 8f0eb24f1a ipv4: prevent potential spectre v1 gadget in fib_metrics_match() 
[ Upstream commit 5e9398a26a ]

if (!type)
        continue;
    if (type > RTAX_MAX)
        return false;
    ...
    fi_val = fi->fib_metrics->metrics[type - 1];

@type being used as an array index, we need to prevent
cpu speculation or risk leaking kernel memory content.

Fixes: 5f9ae3d9e7 ("ipv4: do metrics match when looking up and deleting a route")
