blk_end_request: changing ide-cd (take 4)
This patch converts ide-cd (cdrom_newpc_intr()) to use blk_end_request interfaces. Related 'uptodate' arguments are converted to 'error'. In PIO mode, ide-cd (cdrom_newpc_intr()) needs to defer end_that_request_last() until the device clears DRQ_STAT and raises an interrupt after end_that_request_first(). So blk_end_request() has to return without completing request even if no leftover in the request. ide-cd uses blk_end_request_callback() and a dummy callback function, which just returns value '1', to tell blk_end_request_callback() about that.
