KVM: x86: Invoke kvm_mmu_unload() directly on CR4.PCIDE change
Replace a KVM_REQ_MMU_RELOAD request with a direct kvm_mmu_unload() call when the guest's CR4.PCIDE changes. This will allow tweaking the logic of KVM_REQ_MMU_RELOAD to free only obsolete/invalid roots, which is the historical intent of KVM_REQ_MMU_RELOAD. The recent PCIDE behavior is the only user of KVM_REQ_MMU_RELOAD that doesn't mark affected roots as obsolete, needs to unconditionally unload the entire MMU, _and_ affects only the current vCPU.
