perf, nmi: Fix unknown NMI warning
When using BTS on Core i7-4*, I get the below kernel warning.
$ perf record -c 1 -e branches:u ls

kernel:[ 438.317893] Uhhuh. NMI received for unknown reason 31 on CPU 2.

kernel:[ 438.317920] Do you have a strange power saving mode enabled?

kernel:[ 438.317945] Dazed and confused, but trying to continue
