In descriptor mode, the descriptor running pointer is not maintained by the interrupt handler, thus, driver finds the running descriptor from the descriptor pointer field in the CHCRB register. But, CHCRB::DPTR indicates *next* descriptor pointer, not current. Thus, The residue calculation will be missed. This patch fixup it.
