examples/vhost: fix startup check

For vhost sample, the operation if (dev_info.max_rx_queues >
MAX_QUEUES) in the function port_init causes startup failure
when using X710(i40e driver). X710 requires that MAX_QUEUES
should be defined no less than 320, however it is defined as
128 currently.

Such checking is overkill and Removal don't affect any
functionality (have already validated ixgbe and i40e).

The removal can avoid similar issue when introduing new physical NIC.
