description:
When unloading the module, clear the address of the kauth_listener
after removing the listener.  This enables the module to (attempt to)
initialize again without hitting the KASSERT() is sysvipc_init().

XXX This will allow standard kernels to boot successfully.  However,
XXX module initializtion is still broken.
