[PATCH v3 1/8] KVM: x86/pmu: Rename pmc_is_enabled() to pmc_is_globally_enabled()

[Like Xu]

From: Like Xu <likexu@xxxxxxxxxxx>

The name of function pmc_is_enabled() is a bit misleading. A PMC can
be disabled either by PERF_CLOBAL_CTRL or by its corresponding EVTSEL.
Add the global semantic to its name.
