Subject: [PATCH net-next 2/2] net: stmmac: remove unnecessary stmmac_mac_set()
 in stmmac_release()

stmmac_release() calls phylink_stop() and then goes on to call
stmmac_mac_set(, false). However, phylink_stop() will call
stmmac_mac_link_down() before returning, which will do this work.
Remove this unnecessary call.
