vgsp-gr: retirement wait - exclude every forwarded page from the footprint

r150's first cut excluded only QMD-word pages; the fill also relocates the
0xffffffff (non-QMD) forwarded pages (pushbuffer/indirect/bank pages) as
high-VA candidates, so out_base landed on the bank-page group, out_pages
came out 3 and the wait exited after 72 ms - losing the late-write capture
it exists for (smiley r150: '0/3 pages changed after 72 ms (no writes)'
followed by mixed 8-changed/0-changed/32-changed copy-outs and one wrong
pass). Now every forwarded page VA is excluded, so the footprint is the
real output operand (32 pages for smiley, 64 for matmul).
