[PATCH v2] net/e1000: align link updates in em igb and igc

[AKSHATHA S]

The em, igb, and igc PMDs currently update the auto-neg status only
during specific link transitions. Updated the auto-neg status regardless
of link transition so that it is consistent with ixgbe, i40e, and iavf
drivers.

v2: Addressed review comments
