Jiawen Wu e37546ad1f net: wangxun: revert the adjustment of the IRQ vector sequence 
Due to hardware limitations of NGBE, queue IRQs can only be requested
on vector 0 to 7. When the number of queues is set to the maximum 8,
the PCI IRQ vectors are allocated from 0 to 8. The vector 0 is used by
MISC interrupt, and althrough the vector 8 is used by queue interrupt,
it is unable to receive packets. This will cause some packets to be
dropped when RSS is enabled and they are assigned to queue 8.

So revert the adjustment of the MISC IRQ location, to make it be the
last one in IRQ vectors.
