[dpdk-dev] [PATCH v2] event/octeontx2: fix queue removal from Rx adapter

[Lukasz Bartosik <lbartosik@marvell.com>]

When eth port queue is removed from Rx adapter using
rte_event_eth_rx_adapter_queue_del() it incorrectly
initializes CQ context instead of modifying it. This
might lead to a crash when CQ context is modified
as a part of rte_eth_dev_stop() sequence as CQ will
hold invalid entries. This is responsibility of an
application to call rte_event_eth_rx_adapter_queue_del()
to remove eth port queue from Rx adapter in tear down
sequence.
