When DynamicEx PCD is only used in PEI code, but not DXE code, current implementation of DxePcdGetNextTokenSpace does not assign TmpTokenSpaceBufferCount correctly, but leaves it as initial value, then DxePcdGetNextTokenSpace may return incorrect token space guid and status.
This patch is to fix this issue.
