Finding a buffer that isn't uptodate doesn't invalidate the mapping for
any given block. The last_sector check will already take care of starting
another ioend as soon as we find any non-update buffer, and if the current
mapping doesn't include the next uptodate buffer the xfs_imap_valid check
will take care of it.
