LoongArch: mm: Fix huge page entry update for virtual machine
In virtual machine (guest mode), the tlbwr instruction can not write the last entry of MTLB, so we need to make it non-present by invtlb and then write it by tlbfill. This also simplify the whole logic. Signed-off-by: Rui Wang <wangrui@loongson.cn> Signed-off-by: Huacai Chen <chenhuacai@loongson.cn>
