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.
