KVM: ppc: optimize kvm stat handling
Currently we use an unnecessary if&switch to detect some cases. To be honest we don't need the ligh_exits counter anyway, because we can calculate it out of others. Sum_exits can also be calculated, so we can remove that too. MMIO, DCR and INTR can be counted on other places without these additional control structures (The INTR case was never hit anyway). The handling of BOOKE_INTERRUPT_EXTERNAL/BOOKE_INTERRUPT_DECREMENTER is similar, but we can avoid the additional if when copying 3 lines of code. I thought about a goto there to prevent duplicate lines, but rewriting three lines should be better style than a goto cross switch/case statements (its also not enough code to justify a new inline function).
