x86: Move notify_die from nmi.c to traps.c
In order to handle a new nmi_watchdog approach, I need to move
the notify_die() routine out of nmi_watchdog_tick() and into
default_do_nmi(). This lets me easily swap out the old
nmi_watchdog with the new one with just a config change.
The change probably makes sense from a high level perspective
because the nmi_watchdog shouldn't be handling notify_die
routines anyway. However, this move does change the semantics a
little bit. Instead of checking on every nmi interrupt if the
cpus are stuck, only check them on the nmi_watchdog interrupts.
v2: Move notify_die call into #idef block
