Subject: [PATCH V4 05/14] perf/x86/intel: Fix the name of perf capabilities for perf METRICS

From: Kan Liang <kan.liang@...ux.intel.com>

Bit 15 of PERF_CAPABILITIES MSR indicates this architecture provides
built in support for perf METRICS. The perf METRICS is not a PEBS
feature.

Rename pebs_metrics_available perf_metrics.

No one use the bit in current code. The following patch will use it.
