amd-xgbe: do not double read link status

Browse source

[ Upstream commit 16ceda2ef6 ]

The link status is latched low so that momentary link drops
can be detected. Always double-reading the status defeats this
design feature. Only double read if link was already down

This prevents unnecessary duplicate readings of the link status.
