i40e: prepare for XDP metadata ops support

Browse source

Prepare 'struct i40e_xdp_buff' that contains an xdp_buff and a pointer
to i40e_rx_desc in order to pass the RX descriptor to the XDP kfuncs.
Also in ZC path, use XSK_CHECK_PRIV_TYPE() to ensure i40e_xdp_buff
doesn't exceed the offset of cb in xdp_buff_xsk.

No functional changes.
