perfcounters, x86: simplify disable/enable of counters
Impact: fix spurious missed counter wakeups In the case of NMI events, close a race window that can occur if an NMI hits counter code that temporarily disables+enables a counter, and the NMI leaks into the disabled section. Signed-off-by: Ingo Molnar <mingo@elte.hu>
