  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")

I can see both 'ENA_WAIT_EVENT_DESTROY' & 'ENA_WAIT_EVENTS_DESTROY' does nothing
but, according their definitions:
 +#define ENA_WAIT_EVENT_DESTROY(admin_queue) ((void)(admin_queue))
 +#define ENA_WAIT_EVENTS_DESTROY(waitqueue) ((void)(waitqueue)

If 'ENA_WAIT_EVENTS_DESTROY' also gets 'admin_queue' as parameter, does it make
sense to update the definition of it to get 'admin_queue', like:
 #define ENA_WAIT_EVENTS_DESTROY(admin_queue) ((void)(admin_queue)

And I can see that is updated in next patches, so may be better to update here.

I agree, the ENA_WAIT_EVENTS_DESTROY() should take as an argument
admin_queue. The ENA_WAIT_EVENT_DESTROY shouldn't be touched by this
patch. I will fix that in v4.
