fs/sysv: Don't round down address for kunmap_flush_on_unmap()
The kernel virtual address passed to kunmap_flush_on_unmap() has no more
any need to be rounded down.
Therefore, delete the rounding down of "page_addr" when passed to
kunmap_local() in dir_put_page().
Don't backport without commit 88d7b12068b9 ("highmem: round down the
address passed to kunmap_flush_on_unmap()").
