        src/sys/dist/ipf/netinet: ip_fil_netbsd.c

Log Message:
When IPFilter 4.1.29 has been imported, the mbuf argument to nd6_output()
has been changed from m0 to *mpp. But as *mpp has been set to NULL just
before the call, we end up calling ether_output() with a NULL mbuf,
leading to a NULL pointer dereference. Revert back to using m0 here.

The issue show up when using 'return-rst' or 'return-icmp' in ipf6.conf.
Problem discovered and fix tested on ftp.fr.netbsd.org.
