[dpdk-dev] [PATCH v4 06/19] net/ena/base: destroy multiple "wait events"

Although the ENA DPDK PMD doesn't have to perform any actions for
destroying the wait event, some other platforms have to.
The macro "ENA_WAIT_EVENT_DESTROY" was renamed to
"ENA_WAIT_EVENTS_DESTROY" and also whole implementation responsible for
that was moved to a separate function for better readability.
Fixes: 3adcba9a8987 ("net/ena: update HAL to the newer version")
