REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3418 According to xhci spec, at USB packet level, a Control Transfer consists of multiple transactions partitioned into stages: a setup stage, an optional data stage, and a terminating status stage. If Data Stage does not exist, the Transfer Type flag(TRT) should be No Data Stage. So if data length equals to 0, TRT is set to 0.
