[Bro] Netmap Seg faults

[Johanna Amann]

Is this on FreeBSD or on Linux? :)

In any case, on FreeBSD I hae not seen segfaults with Bro & Netmap on a
broctl stop; however, some machines of us still like to crash when
starting up Bro in the same configuration. (Crash as in apparently
kernel-crash and reboot).
