ide-{floppy,tape}: cleanup ide*_end_request()
* ide*_end_request() is only called with uptodate == 0 or uptodate == 1
so cleanup it accordingly.
* Inline ide*_end_request() content at call sites so the only user left
is ->end_request method.
* ->end_request is now used only for private driver requests so remove
handling of other requests from ide*_end_request().
There should be no functional changes caused by this patch.
