ionic: disable napi when ionic_lif_init() fails
When the driver is going through reset, it will eventually call
ionic_lif_init(), which does a lot of re-initialization. One
of the re-initialization steps is to setup the adminq and
enable napi for it. If something breaks after this point
we can end up with a kernel NULL pointer dereference through
ionic_adminq_napi.
Fix this by making sure to call napi_disable() in the cleanup
path of ionic_lif_init(). This forces any pending napi contexts
to finish and prevents them from being recalled before deleting
the napi context.
Fixes: 77ceb68e29cc ("ionic: Add notifyq support")
