Subject: [PATCH] Fix bug: Incorrect error code return from PmuRead

On some environment which does not support SPE, error code will be returned from PmuRead.
But currently PmuRead always return SUCCESS.
Set SUCCESS before calling Read(), if there is any error code in Read(),
SUCCESS will be override.
