open-iov.git/tools/guest-diag/bp999.py, branch m31Open-IOV vGPU-IO: host-side GSP emulation for unmodified NVIDIA guest drivers

A freed client's notifier events (hSrcResource 0) stayed valid in the event
table, so the fallback wake-up nudge kept posting POST_EVENT records for a
(hClient, hEvent) pair the guest RM no longer knows; every one asserts in
CliGetEventInfo (kernel_gsp.c:466) and is dropped (171 failures in the
15:24 window of the last run, zero after this fix). FREE now retires the
matching event record (and a client's records when its root object is freed).
bp999.py now walks rdi -> ctx -> ctx[0x1291] -> +0x10 -> +0x10 and prints the
RM error notification record, and push_guest_tools.sh ships it to the guest.
