[IPV4/IPV6]: Replace spin_lock_irq with spin_lock_bh
In light of my recent patch to net/ipv4/udp.c that replaced the
spin_lock_irq calls on the receive queue lock with spin_lock_bh,
here is a similar patch for all other occurences of spin_lock_irq
on receive/error queue locks in IPv4 and IPv6.
In these stacks, we know that they can only be entered from user
or softirq context. Therefore it's safe to disable BH only.
