[PATCH] realtek: drop ethtool log noise

[Bjørn Mork]

phylink_mac_link_state calls can be triggered by userspace, and
might happen rather often in some settings like when running snmp
daemons.

One more patch I forgot I've been using.

This log line is pretty annoying in combination with mini_snmpd
with ethtool support (coming soon - waiting for next mini_snmpd
release).   I get a useless log line every second:
