This patchset fixes few issues related to virtio queue reconfigure:
increase or shrink the queue number. The major issue and the reason
behind is described with length details in patch 4 "net/virtio: allocate
queue at init stage".

Those bugs can not be fixed by few lines of code, it's because the
current driver init logic is quite wrong, that I need change quite many
places to make it right. Meanwhile, I have already done my best to keep 
the changes being as minimal as possible, so that we could have fewer
changes to break something else; also, it's would be easier for review.

v2: - fix two more minor issues regarding to queue enabling; see patch 9
      and 10.
    - refined commit log a bit.
