kgdb: fix NMI hangs
This patch fixes the hang regression with kgdb when the NMI interrupt
comes in while the master core is returning from an exception.
Adjust the NMI logic such that KGDB will not stop NMI exceptions from
occurring by in general returning NOTIFY_DONE. It is not possible to
distinguish the debug NMI sync vs the normal NMI apic interrupt so
kgdb needs to catch the unknown NMI if it the debugger was previously
active on one of the cpus.
