KVM: x86/pmu: Rename reprogram_counters() to clarify usage

Browse Source 
Rename reprogram_counters() to kvm_pmu_request_counters_reprogram()
clarifying that it is more similar to
kvm_pmu_request_counter_reprogram(), and less similar to
reprogram_counter(). The kvm_pmu_* prefix is also appropriate as the
function is exposed in the header.

Opportunistically rename the argument from 'diff' to 'counters'.

No functional change intended.
