[PATCH] KVM: fix kvm_mmu_memory_cache allocation warning

[Arnd Bergmann <arnd@kernel.org>]

From: Arnd Bergmann <arnd@arndb.de>

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.

Fixes: 837f66c71207 ("KVM: Allow for different capacities in kvm_mmu_memory_cache structs")
