net: tun: unlink NAPI from device on destruction
Syzbot found a race between tun file and device destruction.
NAPIs live in struct tun_file which can get destroyed before
the netdev so we have to del them explicitly. The current
code is missing deleting the NAPI if the queue was detached
first.
Fixes: 943170998b20 ("tun: enable NAPI for TUN/TAP driver")
