macio: set res_count value to 0 after non-block ATAPI DMA transfers
res_count should be set to the number of outstanding bytes after a DBDMA request. Unfortunately this wasn't being set to zero by the non-block transfer codepath meaning drivers that checked the descriptor result for such requests (e.g reading the CDROM TOC) would assume from a non-zero result that the transfer had failed.
