The comments in arch/{mips,loongarch}/kvm/mmu.c refer to a non-existent
function "pfn_to_pfn_prot". This is a historical typo.
In MIPS, it was introduced in commit 411740f5422a ("KVM: MIPS/MMU:
Implement KVM_CAP_SYNC_MMU") where the actual function being called was
`gfn_to_pfn_prot`.
(see `pfn = gfn_to_pfn_prot(kvm, gfn, write, &writeable);`).
This was later replaced by `kvm_faultin_pfn()` in commit 7e8f1aa59d0b
("KVM: MIPS: Use kvm_faultin_pfn() to map pfns into the guest").
The LoongArch code, likely copied from MIPS, inherited this typo upon
its introduction in commit 752e2cd7b4fb ("LoongArch: KVM: Implement
kvm mmu operations"). The actual function call was likewise updated to
`kvm_faultin_pfn()` in commit 14d02b7ff912 ("KVM: LoongArch: Use
kvm_faultin_pfn() to map pfns into the guest").
Update the comments in both files to correctly reference the current
function, `kvm_faultin_pfn`.
No functional change; comments only.
