Transfer TRBs have a flag that indicates that data is transferred within the TRB itself instead of as a separate buffer. Add support for this type of transfer in the ScatterGatherBuffer implementation. This fixes USB support when using Linux 5.1+ as the guest kernel, since it now uses immediate data transfers.
