pmap_emulate_reference: don't ever lose PV_TABLE_MOD bit on page. If
PV_TABLE_REF cleared before PV_TABLE_MOD, the page may get fault on read again.

On fault on write, pmap_emulate_reference mark the page dirty with
vm_page_dirty. That decrease ill effects of the bug.

The problem probably become more serious after my rev.1.18 a week ago.
