KVM: s390: handle_tprot: Honor storage keys
Use the access key operand to check for key protection when
translating guest addresses.
Since the translation code checks for accessing exceptions/error hvas,
we can remove the check here and simplify the control flow.
Keep checking if the memory is read-only even if such memslots are
currently not supported.
handle_tprot was the last user of guest_translate_address,
so remove it.
