perf, x86: Fix incorrect branches event on AMD CPUs
commit f287d332ce835f77a4f5077d2c0ef1e3f9ea42d2 upstream.
While doing some performance counter validation tests on some
assembly language programs I noticed that the "branches:u"
count was very wrong on AMD machines.
It looks like the wrong event was selected.
