Checking this a bit now and I'm not sure if we have the same problem. On
alloc_param_target() the cleanup is simply kfree(nt).
free_param_target() is only called as part of netconsole module setup/cleanup
but
only for targets that were succesfully added to the target list (so are
guaranteed
to have resume_wq initialised) before we hit the error.
Let me know if I'm missing something!
