    x86/nmi: Drop K7_NMI_EVENT
    
    This name is misleading.
    
    It's not possible to configure NMI or not from the event select register; 
that
    comes from the APIC configuration for performance events.
    
    This name is "the thing we want to count for the NMI watchdog", but that's
    clearer to follow when it simply names the event.  Drop the indirection.
    
    No functional change.
