guest-diag: cycle monitor CPUs on kernel-VA translation failure
HMP x/gva2gpa translate with the selected vCPU's CR3; while that CPU runs
user code under PTI the kernel half is hidden, so kernel-VA reads (the
tracking-sem chain and the CE pushbuffer CPU alias) fail and the pin pass
aborts. Try the other vCPUs before giving up: during an active CUDA client
at least one CPU is in kernel mode, so the chain/pin work no longer require
the client to be parked in sleep().
