perf, x86: Fix Intel-nhm PMU programming errata workaround
Fix the Errata AAK100/AAP53/BD53 workaround, the officialy documented
workaround we implemented in:
11164cd: perf, x86: Add Nehelem PMU programming errata workaround
doesn't actually work fully and causes a stuck PMU state
under load and non-functioning perf profiling.
A functional workaround was found by trial & error.
Affects all Nehalem-class Intel PMUs.
