Hopefully bad tests will cause the module to not insert, so the CI picks
this up. It looks like a failure to insert the module at the moment
actually causes another crash, though:

exclusive sleep mutex if_cloners lock (if_cloners lock) r = 0 (0xffffffff81d9a9b8) locked @ /usr/src/sys/net/if_clone.c:447
