net: korina: Fix NAPI versus resources freeing
commit e6afb1ad88feddf2347ea779cfaf4d03d3cd40b6 upstream.
Commit beb0babfb77e ("korina: disable napi on close and restart")
introduced calls to napi_disable() that were missing before,
unfortunately this leaves a small window during which NAPI has a chance
to run, yet we just freed resources since korina_free_ring() has been
called:
Fix this by disabling NAPI first then freeing resource, and make sure
that we also cancel the restart task before doing the resource freeing.
