ide: add ide_retry_pc() helper
* Add ide_create_request_sense_cmd() and ide_retry_pc() helpers
and convert ide-{atapi,floppy,tape}.c to use them.
* Remove no longer used ide*_create_request_sense_cmd(),
ide*_retry_pc() and 'retry_pc' argument from ide_pc_intr().
* Make ide_queue_pc_head() static.
There should be no functional changes caused by this patch.
