igc: Expose LPI counters 



Completion to commit 900d1e8b ("igc: Add LPI counters")
LPI counters exposed by statistics update method.
A EEE TX LPI counter reflect the transmitter entries EEE (IEEE 802.3az)
into the LPI state. A EEE RX LPI counter reflect the receiver link
partner entries into EEE(IEEE 802.3az) LPI state.
