KVM: MMU: Clean up MMU functions to take struct kvm when appropriate
Some of the MMU functions take a struct kvm_vcpu even though they affect all
VCPUs. This patch cleans up some of them to instead take a struct kvm. This
makes things a bit more clear.
The main thing that was confusing me was whether certain functions need to be
called on all VCPUs.
