This patch fixes the queue pair configuration for the scheduler PMD.
The queue pairs of a scheduler may have different nb_descriptors sizes,
which was not the case. Also, the maximum available objects in a
queue pair is 1 object smaller than nb_descriptors. This patch fixes
these issues.
Fixes: 4987bbaa4810 ("crypto/scheduler: add packet size based mode")

Wrong fixes line -> Changed to "a783aa634410 ("crypto/scheduler: add packet size based mode")".
Also, this patch doesn't need to go to stable tree, as it is fixing a commit
that was sent in this release.
Applied to dpdk-next-crypto.
Thanks,
Pablo
