block: Do not force full zone append completion in req_bio_endio()

commit 55251fbdf0146c252ceff146a1bb145546f3e034 upstream.

This reverts commit 748dc0b65ec2b4b7b3dbd7befcc4a54fdcac7988.

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 748dc0b65ec2 ("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.
