[dpdk-dev] config:enlarge the default value of RTE_MAX_QUEUES_PER_PORT to 1024

  The default value of RTE_MAX_QUEUES_PER_PORT is 256, which is too small for some configurations for i40e. There will return an error when configured queue number is larger than 256 in 

rte_eth_dev_configure().

For example, in vHost sample, PF queue number: 64, configured vmdq pool number: 63, each vmdq pool has 4 queues, there will be required 316 queues in a port.
