gr: r405 restore the no-write classifier input - propagate the tracked page total to the retire-wait out-param
ed91540a (r345) changed gsp_phys_gr_scan_pages to return the changed
count and report the tracked total through an out-param, but the caller
saved it into a local and never wrote *n_tracked. Every launch since
reported n_tracked=0, so the caller gate (wrote == 0 && n_tracked) was
never true: the first-attempt witness, the outcome re-execution retries
(fresh qmdwin bank + release zeroing + re-publish), the NOWRITE accept
with release-word restore, and the late-store check have all been dead
code. The r404 forensics show the regression directly: 'RETIRE-WIT
n_data=968 n_tracked=0' beside 'output retirement wait: 0/1032 pages
changed (no writes)' for the same launch. Propagate n_all so the
classifier fires again.
