guest-diag: ctx999.py (scanner/ctx gdb capture); fix pinner exact-VA match
ctx999.py arms the scanner entry/returns plus cuCtxCreate and dumps the
ctx->mgr->reg->record chain at the stop. First live capture: the scanner is
called with param_2=1 during normal context creation and correctly returns 0
on a zero record (mgr[+0], the channel handle, and the record walk are now
confirmed live). pin_miss_pages.sh must match the exact VA pmapall printed:
guest_pmap_all.py returns the first nvidia page at-or-above va-min, so a page
that is not present resolves to an unrelated mapping (it pinned a UVM page
for 0x20400f000).
