Summary
pktgen: use cpus_read_lock() in pg_net_init()
Details

In the Linux kernel, the following vulnerability has been resolved:

pktgen: use cpusreadlock() in pgnetinit()

I have seen the WARNON(smpprocessorid() != cpu) firing in pktgenthread_worker() during tests.

We must use cpusreadlock()/cpusreadunlock() around the foreachonline_cpu(cpu) loop.

While we are at it use WARNONONCE() to avoid a possible syslog flood.
