The number of queues was limited by number of lcores in the recent ENAv2
patch. However, some apps like symmetric_mp, are configuring multiple
queues although there is only single lcore used.

To prevent failure in that case, the lcore number constraint was
removed.

Fixes: ea93d37eb49d ("net/ena: add HW queues depth setup")
