ide: ide_lock + __blk_end_request() -> blk_end_request()

Browse Source 
Use blk_end_request() instead of ide_lock + __blk_end_request()
in cdrom_end_request(), cdrom_newpc_intr(), __ide_end_request(),
ide_complete_pm_request() and ide_end_drive_cmd().

[ ide_lock is currently also used as queue lock ]
