Currently, when debugging AF_XDP workloads, one can correlate the -ENXIO return code as the case that XSK is not in the bound state. Returning same code from ndo_xsk_wakeup can be misleading and simply makes it harder to follow what is going on. Change ENXIOs in i40e's ndo_xsk_wakeup() implementations to EINVALs, so that when probing it is clear that something is wrong on the driver side, not in the xsk_{recv,send}msg. There is a -ENETDOWN that can happen from both kernel/driver sides though, but I don't have a correct replacement for this on one of the sides, so let's keep it that way.
