KVM: x86: Tag kvm_mmu_x86_module_init() with __init
Mark kvm_mmu_x86_module_init() with __init, the entire reason it exists
is to initialize variables when kvm.ko is loaded, i.e. it must never be
called after module initialization.
Fixes: 1d0e84806047 ("KVM: x86/mmu: Resolve nx_huge_pages when kvm.ko is loaded")
