examples/vhost: fix hard forward of jumbo frames

Search the right segment to increase its data length, rather than
wrongly early return and exit the tx function, which leads to drop all jumbo frame packets
when vm2vm is in hard forward mode.

examples/vhost: increase maximum queue number

Increase MAX_QUEUES from 256 to 512.

In vhost example, MAX_QUEUES macro should be the maximum possible queue number of the port.
Theoretically we should only set up the queues that are used, i.e., first rx queue of each pool, or
at most queues from 0 to MAX_QUEUES. Before we revise the implementation and are certain all NICs support
this well, add a remind message to user.

calling rte_eth_dev_info_get, just before setting up RX/TX queues."

examples/vhost: support new VMDQ API for i40e

In Niantic, if VMDQ mode is set, all queues are allocated to VMDQ in DPDK.
In I40E, only configured part of continous queues are allocated to VMDQ.
The rte_eth_dev_info structure is extended to provide VMDQ queue base,
queue number, and VMDQ pool base information.
This patch support the new VMDQ API in vhost example.

FIXME in PMD:
* added mac address will be flushed at rte_eth_dev_start.
* we don't support selectively setting up queues well.
