tun: initialize napi_mutex unconditionally
This is the first part to fix following syzbot report :
console output: https://syzkaller.appspot.com/x/log.txt?x=145378e6400000
kernel config: https://syzkaller.appspot.com/x/.config?x=443816db871edd66
dashboard link: https://syzkaller.appspot.com/bug?extid=e662df0ac1d753b57e80
Following patch is fixing the race condition, but it seems safer
to initialize this mutex at tfile creation anyway.
Fixes: 90e33d459407 ("tun: enable napi_gro_frags() for TUN/TAP driver")
