[dpdk-dev] [PATCH] test/crypto: refactor scheduler test worker PMDs

[Rebecca Troy <rebecca.troy@intel.com>]

Previously, the scheduler unit test only created and attached 1 or 2
AESNI-MB cryptodev PMDs as workers if less than 2 AESNI-MB PMDs had
already been initialized.

This commit changes this to always create and attach 2 new AESNI-MB
cryptodev PMDs, regardless of previously initialized AESNI-MB PMDs.
