The octeontx event device doesn't store the queues to port mapping as a result
it cannot return the exact number of queues unlinked from a port when
application wants to unlink all the queues mapped (supplies queues param as
NULL).
Using links_map we can determine the exact queues mapped to a specific port and
unlink them.
