[PATCH ethtool] ethtool.8: Remove "default" note about rxfh xfrm

Since linux.git commit 4d20c9f2db83 ("net/mlx5e: Symmetric OR-XOR RSS hash
control"), the default rxfh xfrm used by mlx5 devices is
'symmetric-or-xor'. Since the default xfrm is driver-dependent and
ethtool.8 does not document the default values implemented by drivers,
remove the comment from ethtool.8 which says that the default xfrm is
'none'.
