ide-cd: use common completion path for DMA requests in cdrom_newpc_intr()
Use the following facts:
- rq->nr_sectors should now be always equal to (non-zero)
rq->hard_nr_sectors for fs requests
- REQ_TYPE_ATA_PC requests have never bio attached to them
- rq->hard_nr_sectors == 0 for REQ_TYPE_ATA_PC requests
- DMA is used only for fs, pc and REQ_TYPE_ATA_PC requests
- 'uptodate' is ignored for pc requests ('rc == 0' case)
and use the common completion path also for DMA requests.
There should be no functional changes caused by this patch
