KVM: PPC: Use __kvm_faultin_pfn() to handle page faults on Book3s HV

Replace Book3s HV's homebrewed fault-in logic with __kvm_faultin_pfn(),
which functionally does pretty much the exact same thing.

Note, when the code was written, KVM indeed didn't do fast GUP without
"!atomic && !async", but that has long since changed (KVM tries fast GUP
for all writable mappings).
