Subject: [PATCH net 1/1] net: stmmac: remove redunctant disable xPCS EEE call

Disable is done in stmmac_init_eee() on the event of MAC link down.
Since setting enable/disable EEE via ethtool will eventually trigger
a MAC down, removing this redunctant call in stmmac_ethtool.c to avoid
calling xpcs_config_eee() twice.

Fixes: d4aeaed80b0e ("net: stmmac: trigger PCS to turn off on link down")
