USB: xhci: Set TD size in transfer TRB.

The 0.95 xHCI specification requires software to set the "TD size" field
in each transaction request block (TRB).  This field gives the host
controller an indication of how much data is remaining in the TD
(including the buffer in the current TRB).  Set this field in bulk TRBs
and data stage TRBs for control transfers.
