KVM: fix kvm_mmu_memory_cache allocation warning
gcc-14 notices that the arguments to kvmalloc_array() are mixed up: arch/x86/kvm/../../../virt/kvm/kvm_main.c: In function '__kvm_mmu_topup_memory_cache': arch/x86/kvm/../../../virt/kvm/kvm_main.c:424:53: error: 'kvmalloc_array' sizes specified with 'sizeof' in the earlier argument and not in the later argument [-Werror=calloc-transposed-args] 424 | mc->objects = kvmalloc_array(sizeof(void *), capacity, gfp); | ^~~~ arch/x86/kvm/../../../virt/kvm/kvm_main.c:424:53: note: earlier argument should specify number of elements, later size of each element The code still works correctly, but the incorrect order prevents the compiler from properly tracking the object sizes.
