Subject: [PATCH net-next] pktgen: Fix unsigned function that is returning negative vals

Every call to num_args() immediately checks the return value for
less than zero, as it will return -EFAULT for a failed get_user()
call.  So it makes no sense for the function to be declared as an
unsigned long.
