rS340783: Plug some networking sysctl leaks.

Summary

Various networking sysctls don't zero-fill their output and thus leak
padding bytes, mostly from the stack. Based on a report I audited a
number of sysctl handlers, especially those which export pcblists, and
fixed a number of leaks, some of which are quite large.
