vgsp-sema: a stale-dropped pool read must not consume the residue rule (second-client fix)

r99/r100: the fresh session's reused pool page reads the previous session's
residue (cur=2) before the first genuine release (pay=1) is translated; the
translated read set ch->pool_rel_seen, so every later residue release
(payload <= cur) was silently dropped by the final else and the client spun
at DEVICE forever. A read that applied or deferred nothing now leaves the
flag clear so the r63/r64 residue re-seed still fires for the first genuine
release of the session.
