usb: musb: musb_cppi41: factor most of cppi41_dma_callback() into cppi41_trans_done()
This patch moves most of the logic in cppi41_dma_callback() into cppi41_trans_done() where it can be called from another function. Instead of computing "transferred" (the number of bytes transferred in the last transaction) in cppi41_trans_done() the member "cppi41_channel->prog_len" is now set to 0 if the transfer as a whole can be considered as done. If it is != 0 then the next iteration is assumed. This is a preparation for a workaround.
