xtensa: ISS: fix locking in TAP network adapter
- don't lock lp->lock in the iss_net_timer for the call of iss_net_poll,
it will lock it itself;
- invert order of lp->lock and opened_lock acquisition in the
iss_net_open to make it consistent with iss_net_poll;
- replace spin_lock with spin_lock_bh when acquiring locks used in
iss_net_timer from non-atomic context;
- replace spin_lock_irqsave with spin_lock_bh in the iss_net_start_xmit
as the driver doesn't use lp->lock in the hard IRQ context;
- replace __SPIN_LOCK_UNLOCKED(lp.lock) with spin_lock_init, otherwise
lockdep is unhappy about using non-static key.
