vhost: fix crash on NUMA

vhost: fix crash on NUMA

The queue allocation was changed, from allocating one queue-pair at a
time to one queue at a time. Most of the changes have been done, but
just with one being missed: the size of copying the old queue is still
based on queue-pair at numa_realloc(), which leads to overwritten issue.
As a result, crash may happen.

Fix it by specifying the right copy size. Also, the net queue macros
are not used any more. Remove them.
