Toshiaki Makita 6e8cfd6d9d tun: Fix use-after-free on XDP_TX
On XDP_TX we need to free up the frame only when tun_xdp_tx() returns a
negative value. A positive value indicates that the packet is
successfully enqueued to the ptr_ring, so freeing the page causes
use-after-free.

Fixes: 735fc4054b ("xdp: change ndo_xdp_xmit API to support bulking")
