  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")

Signed-off-by: Fan Zhang <roy.fan.zhang@intel.com>

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