raw: Restore /proc/net/raw correct behavior

I just noticed "cat /proc/net/raw" was buggy, missing '\n' separators.

I believe this was introduced by commit 8cd850efa4948d57a2ed836911cfd1ab299e89c6 
([RAW]: Cleanup IPv4 raw_seq_show.)

This trivial patch restores correct behavior, and applies to current 
Linus tree (should also be applied to stable tree as well.)
