When rte_event_crypto_adapter_create() 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 is no longer need to configure the
eventdev with ``rte_event_dev_config::nb_single_link_event_port_queues``
parameter required for crypto adapter when the adapter is created
using above mentioned api.
