[PATCH] sky2: netpoll on dual port cards 

The sky2 driver uses a single NAPI poll routine for both ports on dual ported
cards (because there is a single IRQ and status ring). Netpoll makes assumptions
about the relationship between network device and NAPI that aren't correct
on the second port, this will cause the port to never clear work.

Most systems, just have single port, so not a big issue.
The easy fix is just make the second port, not netpoll capable.
