[dpdk-dev] [PATCH v2] crypto/scheduler: fix possible duplicated ring names

[Fan Zhang]

This patch fixes the possible duplicated ring names in multi-core
scheduler. Originally two or more multi-core schedulers may have
same worker ring names thus will cause initialization error.

Fixes: 4c07e0552f0a ("crypto/scheduler: add multicore scheduling mode")

v2:
- changed fix line location
- used device id and index to generate unique pool name
