Maciej Żenczykowski 474ff26008 net-ethtool: ETHTOOL_GUFO did not and should not require CAP_NET_ADMIN
So it should not fail with EPERM even though it is no longer implemented...

This is a fix for:
  (userns)$ egrep ^Cap /proc/self/status
  CapInh: 0000003fffffffff
  CapPrm: 0000003fffffffff
  CapEff: 0000003fffffffff
  CapBnd: 0000003fffffffff
  CapAmb: 0000003fffffffff

  (userns)$ tcpdump -i usb_rndis0
  tcpdump: WARNING: usb_rndis0: SIOCETHTOOL(ETHTOOL_GUFO) ioctl failed: Operation not permitted
  Warning: Kernel filter failed: Bad file descriptor
  tcpdump: can't remove kernel filter: Bad file descriptor

With this change it returns EOPNOTSUPP instead of EPERM.

Fixes: 08a00fea6d "net: Remove references to NETIF_F_UFO from ethtool."
