ixgbe: cleanup crosstalk fix

This patch address a few issues with the initial crosstalk fix.  Most
important of which is the SDP that indicates the presents of a SFP+

to consideration

It also moves the check closer to the base code that checks link.  This
makes it so we only need to do the check in one spot.
