m/node: panic on unknown NMIs

Configure the kernel to panic in case it receives an unknown NMI.

This can be used to induce a crash in a hanging kernel, allowing
crash diagnostics (pstore currently, maybe kdump in the future) to be
used to diagnose the hang.

This can have false positives on some badly-configured client systems,
but is expected to be fine on servers as other server kernels like
ESXi's vmkernel behave the same.
