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 :-)
