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;
          |                             ^~~~~~~
