Damien Le Moal 244cb8200e block: Do not force full zone append completion in req_bio_endio()
commit 55251fbdf0 upstream.

This reverts commit 748dc0b65e.

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 748dc0b65e ("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.

Fixes: 748dc0b65e ("block: fix partial zone append completion handling in req_bio_endio()")
