KVM: nVMX: WARN on failure to set IA32_PERF_GLOBAL_CTRL

Browse source

Writes to MSR_CORE_PERF_GLOBAL_CONTROL should never fail if the VM-exit
and VM-entry controls are exposed to L1. Promote the checks to perform a
full WARN if kvm_set_msr() fails and remove the now unused macro
SET_MSR_OR_WARN().
