Previously if a cached file had grown larger than the remote object
and the cached range metadata was out of sync with the cache file
(e.g. after an unclean shutdown) - reloading the file failed with an
"invalid seek position" error. This aborted the writeback and left the
file inaccessible.
Rclone now recovers the bytes that are still available from the remote
and logs an ERROR that the local file is likely corrupted after an
interrupted upload.
See #9231.
