net: ena: Introduce total_tx_size field in ena_tx_buffer struct

Browse source

To avoid de-referencing skb or xdp_frame when we poll for TX completion
(where they might not be in the cache), save the total TX packet size in
the ena_tx_buffer object representing the packet.

Also the 'print_once' field's type was changed from u32 to u8 to allow
adding the 'total_tx_size' without changing the total size of the
struct.
