[dpdk-dev] [PATCH] drivers/qat: fix failure to create PMD

[Fiona Trahe <fiona.trahe@intel.com>]

If QAT crypto pmd failed to be created due to reaching max allowed
cryptodevs it prevented QAT comp PMD being created. And vice versa.
Change to warning in these cases and allow the other PMD to be created.

Fixes: c0c90bc4cade ("compress/qat: add create and destroy functions")
Cc: stable@dpdk.org
