net/mlx5e: clear xdp features on non-uplink representors

Non-uplink representor port does not support XDP. The patch clears
the xdp feature by checking the net_device_ops.ndo_bpf is set or not.

Verify using the netlink tool:
$ tools/net/ynl/cli.py --spec Documentation/netlink/specs/netdev.yaml --dump dev-get

Representor netdev before the patch:
{'ifindex': 8,
  'xdp-features': {'basic',
                   'ndo-xmit',
                   'ndo-xmit-sg',
                   'redirect',
                   'rx-sg',
                   'xsk-zerocopy'},
  'xdp-rx-metadata-features': set(),
  'xdp-zc-max-segs': 1,
  'xsk-features': set()},
With the patch:
 {'ifindex': 8,
  'xdp-features': set(),
  'xdp-rx-metadata-features': set(),
  'xsk-features': set()},
