netdev-linux: Avoid division by 0 if kernel reports bad scheduler data.
If the kernel reported a value of 0 for the second value in
/proc/net/psched, it would cause a division-by-zero fault in
read_psched(). I don't know of a kernel that would actually do that, but
it's still better to be safe.
Found by clang static analyzer.
