MIPS: KVM: Fix a build warning about variable set but not used
After commit 411740f5422a ("KVM: MIPS/MMU: Implement KVM_CAP_SYNC_MMU")
old_pte is no longer used in kvm_mips_map_page(). So remove it to fix a
build warning about variable set but not used:
arch/mips/kvm/mmu.c: In function 'kvm_mips_map_page':
>> arch/mips/kvm/mmu.c:701:29: warning: variable 'old_pte' set but not used [-Wunused-but-set-variable]
701 | pte_t *ptep, entry, old_pte;
| ^~~~~~~
