block: Do not force full zone append completion in req_bio_endio()
commit 55251fb upstream. This reverts commit 748dc0b. Partial zone append completions cannot be supported as there is no guarantees that the fragmented data will be written sequentially in the same manner as with a full command. Commit 748dc0b ("block: fix partial zone append completion handling in req_bio_endio()") changed req_bio_endio() to always advance a partially failed BIO by its full length, but this can lead to incorrect accounting. So revert this change and let low level device drivers handle this case by always failing completely zone append operations. With this revert, users will still see an IO error for a partially completed zone append BIO.
