Subject: [bpf-next PATCH] net: avoid including xdp.h in filter.h

If is sufficient with a forward declaration of struct xdp_rxq_info in
linux/filter.h, which avoids including net/xdp.h.  This was originally
suggested by John Fastabend during the review phase, but wasn't
included in the final patchset revision.  Thus, this followup.
