highmem: round down the address passed to kunmap_flush_on_unmap()
We already round down the address in kunmap_local_indexed() which is the
other implementation of __kunmap_local(). The only implementation of
kunmap_flush_on_unmap() is PA-RISC which is expecting a page-aligned
address. This may be causing PA-RISC to be flushing the wrong addresses
currently.
