Subject: [PATCH v5 1/4] eventdev/eth_rx: change eventdev reconfig lo= gic
 
When rte_event_eth_rx_adapter_create() or
rte_event_eth_rx_adapter_create_with_params() is used for creating
adapter instance, eventdev is reconfigured with additional
``rte_event_dev_config::nb_event_ports`` parameter.

This eventdev reconfig logic is enhanced to increment the
``rte_event_dev_config::nb_single_link_event_port_queues``
parameter if the adapter event port config is of type
``RTE_EVENT_PORT_CFG_SINGLE_LINK``.

With this change the application no longer need to configure the
eventdev with ``rte_event_dev_config::nb_single_link_event_port_queues`` parameter required for eth_rx adapter when the adapter is created
using above mentioned apis.
