[dpdk-dev] [PATCH] event/octeontx: fix flush callback

[Pavan Nikhilesh <pbhagavatula@caviumnetworks.com>]

When event queues are being flushed the getwork operation used to extract
events should be a grouped getwork operation to the specific event queue.

Fixes: 8384f0e039ea ("event/octeontx: support device stop flush callback")
