[PATCH 2/2] KVM/PPC: Fix kvm_main.c build error for PPC KVM

[Yang Shi]

With the latest kernel building KVM for PPC, got integer overflow
error in kvm_main.c file. The root cause is that compiler consider
KVM_PAGES_PER_HPAGE as signed long type, however it should be
unsigned long type.

So, change it to unsigned long type in include/asm/kvm_host.h
