get_page_addr_code() reads a code tlb entry, but interprets it as an
iotlb entry. This works by accident since the low bits of a RAM code
tlb entry are clear, and match a RAM iotlb entry. This accident is
about to unhappen, so fix the code to use an iotlb entry (using the
code entry with TLB_MMIO may fail if the page is a watchpoint).
