Initial net_device implementation used ingress_lock spinlock to synchronize ingress path of device. This lock was used in both process and bh context. In some code paths action map lock was obtained while holding ingress_lock. Commit e1e992e52faa ("[NET_SCHED] protect action config/dump from irqs") modified actions to always disable bh, while using action map lock, in order to prevent deadlock on ingress_lock in softirq. This lock was removed from net_device, so disabling bh, while accessing action map, is no longer necessary.Replace all action idr spinlock usage with regular calls that do not disable bh.
