Commit eb9a36be7f3e ("sfc: perform XDP processing on received packets") and commit d48523cb88e0 ("sfc: Copy shared files needed for Siena (part 2)") use xdp_rxq_info_valid to track failures of xdp_rxq_info_reg(). However, this driver-maintained state becomes redundant since the XDP framework already provides xdp_rxq_info_is_reg() for checking registration status.
