tun: make tun_build_skb() thread safe
tun_build_skb() is not thread safe since it uses per queue page frag,
this will break things when multiple threads are sending through same
queue. Switch to use per-thread generator (no lock involved).
Fixes: 66ccbc9c87c2 ("tap: use build_skb() for small packet")
