[Description]
Fix ADMAv1/v2 RSS ring memory leak issue.

Due to incorrect memory release method, memory leak issue occurs
when executing network restart. Without SRAM, a single network
restart will leak approximately 98KB of memory.

Without this patch, not using SRAM may lead to memory exhaustion
and cause the system crash.
