skge napi->poll() locking bug
According to: Documentation/networking/netdevices.txt:
<cite>
napi->poll:
..........
Context: softirq
will be called with interrupts disabled by netconsole.
</cite>
napi->poll() could be called either with interrupts enabled
(in softirq context) or disabled (by netconsole), so the irq flag
should be preserved.
Inspired by Ingo's resent forcedeth patch :-)
