Yoshihiro Shimoda 626d2f07de dmaengine: usb-dmac: check CHCR.DE bit in usb_dmac_isr_channel() ...

The USB-DMAC's interruption happens even if the CHCR.DE is not set to 1
because CHCR.NULLE is set to 1. So, this driver should call
usb_dmac_isr_transfer_end() if the DE bit is set to 1 only. Otherwise,
the desc is possible to be NULL in the usb_dmac_isr_transfer_end().
