i40e: fix for PHY NVM interaction problem
This patch fixes a problem where the NVMUpdate Tool, when using the PHY NVM feature, gets bad data from the PHY because of contention on the MDIO interface from get PHY capability calls from the driver during regular operations. The problem is fixed by adding a check if media is available before calling get PHY capability function because that bit is not set when device is in PHY interaction mode.
