x86/boot: Add a message about ignored early NMIs
Commit
78a509fba9c9 ("x86/boot: Ignore NMIs during very early boot")
added an empty handler in early boot stage to avoid boot failure due to
spurious NMIs.
Add a diagnostic message to show that early NMIs have occurred.
[ bp: Touchups. ]
[ Committer note: tested by stopping the guest really early and
injecting NMIs through qemu's monitor. Result:
early console in setup code
Spurious early NMIs ignored: 13
