tuntap: correctly handle error in tun_set_iff()
[ Upstream commit 662ca437e714caaab855b12415d6ffd815985bc0 ]
Commit c8d68e6be1c3b242f1c598595830890b65cea64a
(tuntap: multiqueue support) only call free_netdev() on error in
tun_set_iff(). This causes several issues:
- memory of tun security were leaked
- use after free since the flow gc timer was not deleted and the tfile
were not detached
This patch solves the above issues.
