net: xdp: remove unused bfp_warn_invalid_xdp_buffer()
After commit 73b62bd085f4737679ea9afc7867fa5f99ba7d1b ("virtio-net: remove the warning before XDP linearizing"), there's no users for bpf_warn_invalid_xdp_buffer(), so remove it. This is a revert for commit f23bc46c30ca5ef58b8549434899fcbac41b2cfc.
