[Intel-wired-lan] [next PATCH S2 09/13] i40e: [NVMUpdate] kernel crash after unloading i40e driver

From: Piotr Marczak <piotr.marczak at intel.com>

After NVMUpdate driver is in Recovery Mode and performing reset but
i40e_client is still up. If there is an activity on port which already
is down and its dereference is NULL, client would still dispatch
processing to this PF causing hard kernel crash. This fix prevents
such a situation.
