[PATCH v4 09/11] perf/x86/rapl: Remove the global variable rapl_msrs

[Dhananjay Ugwekar]

After making the rapl_model struct global, the rapl_msrs global
variable isn't needed, so remove it.

Also it will be cleaner when new per-core scope PMU is added. As we will
need to maintain two rapl_msrs array(one for per-core scope and one for
package scope PMU), inside the rapl_model struct.
