lib8390: Fix locking in ei_poll (poll controller)
This lockdep warning:
=================================
[ INFO: inconsistent lock state ]
2.6.27-rc7 #3
---------------------------------
inconsistent {in-softirq-W} -> {softirq-on-W} usage.
syslogd/2474 [HC0[0]:SC0[0]:HE1:SE1] takes:
(_xmit_ETHER#2){-+..}, at: [<c0265562>] netpoll_send_skb+0x132/0x190
...
is caused by unconditional local_irq_disable()/local_irq_enable() in
disable_irq_lockdep()/enable_irq_lockdep() used by __ei_poll(). Since
netconsole/netpoll always calls dev->poll_controller() with local irqs
disabled, disable_irq()/enable_irq() instead is safe and enough (like
e.g. in 3c509 or 8139xx drivers).
