[PATCH v3 01/17] test/bbdev: fix seg fault for non supported HARQ len

[Hernan Vargas]

Fix segmentation fault happening in corner case in test-bbdev.
This fault could happen when running some specific vectors which size
are not supported by the PMD.

[PATCH v3 17/17] test/bbdev: remove iter count from bler test

[Hernan Vargas]

iter_count doesn't need to be set equal to iter_max for bler tests. This
is only needed in throughput and latency tests because early termination
is disabled for those tests.
