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 88d7b12068 ("highmem: round down the
address passed to kunmap_flush_on_unmap()").
