  1ca05831b9b added a check that SDP3 (used as a TX_DISABLE output to the
SFP cage on these cards) is not asserted to avoid incorrectly reporting
link up when the SFP's laser is turned off.

ff8162cb957 limited this workaround to fiber ports

This patch:
* Adds additional check for 82599 type, not all fiber ixgbe devs use
  SDP3 as TX_DISABLE

Fixes: 1ca05831b9b ("net/ixgbe: fix link status")
