x86/nmi: Fix nmi_handle() duration miscalculation
When nmi_check_duration() is checking the time an NMI handler took to
execute, the whole_msecs value used should be read from the @duration
argument, not from the ->max_duration, the latter being used to store
the current maximal duration.
[ bp: Rewrite commit message. ]
