From: Marcin Wilk <marcin.w...@caviumnetworks.com>
Trying to assign more queues to stats struct break only from one loop
when the maximum size is reached. Outside loop iteration is continued.
This leads to access an array out of bounds.
Fixes: 21e3fb0050b9 ("net/thunderx: add final bits for secondary queue support")
