perf/x86: Remove warning for zero PEBS status
The recent commit:
75f80859b130 ("perf/x86/intel/pebs: Robustify PEBS buffer drain")
causes lots of warnings on different CPUs before Skylake
when running PEBS intensive workloads.
They can have a zero status field in the PEBS record when
PEBS is racing with clearing of GLOBAl_STATUS.
This also can cause hangs (it seems there are still
problems with printk in NMI).
Disable the warning, but still ignore the record.
