Eric Dumazet 23dad2d088 tun: no longer rely on RTNL in tun_fill_info()
Update tun_fill_info() to read device configuration fields (flags, owner,
group, numqueues, numdisabled) locklessly using READ_ONCE().

Annotate all writes to these fields in the control paths with WRITE_ONCE()
to prevent data races, as these fields can be modified concurrently via
ioctls (TUNSETPERSIST, TUNSETOWNER, TUNSETGROUP, TUNSETIFF) or queue
attaching/detaching.
