ixgbe: fix regression on some 82598 adapters
The change to check the SFP+ module again on open() was causing the XFP (non-SFP+) adapters to be rejected. We only want to try and re-identify the SFP+ module if the original probe found that this device was an SFP+ device. So for this code path (driver loaded with SFP module, module inserted, ifconfig up of the device) the type will be ixgbe_phy_unknown for an unidentified SFP+ module. So we only check if that is the case. This problem also shows up on Copper devices.
