ethtool: remove set but not used variable 'lsettings'

Fixes gcc '-Wunused-but-set-variable' warning:

net/ethtool/linkmodes.c: In function 'ethnl_set_linkmodes':
net/ethtool/linkmodes.c:326:32: warning:
 variable 'lsettings' set but not used [-Wunused-but-set-variable]
  struct ethtool_link_settings *lsettings;
                                ^
It is never used, so remove it.
