net/ixgbe: fix link status

Browse Source 
The link status for 82599eb got from link status register was not
correct, check the enable/disable flag of tx laser when getting the link
status, set the link status down if tx laser disabled since the tx laser
flag could be set correctly when up/down the link status.

Fixes: dc66e5fd01 ("net/ixgbe: improve link state check on VF")
