tuntap: correctly add the missing XDP flush
We don't flush batched XDP packets through xdp_do_flush_map(), this
will cause packets stall at TX queue. Consider we don't do XDP on NAPI
poll(), the only possible fix is to call xdp_do_flush_map()
immediately after xdp_do_redirect().
Note, this in fact won't try to batch packets through devmap, we could
address in the future.
