update_mmu_tlb() can be used instead of update_mmu_cache() when the
page fault handler detects that it lost the race to another page fault.

It looks like this one call was missed in
https://patchwork.kernel.org/project/linux-mips/patch/1590375160-6997-2-git-send-email-maobibo@loongson.cn
after Andrew asked to replace all update_mmu_cache() calls with an alias
in the previous version of this patch here:
