exec: abstract address_space_do_translate()

This function is an abstraction helper for address_space_translate() and
address_space_get_iotlb_entry(). It does the lookup of address into
memory region section, then does proper IOMMU translation if necessary.
Refactor the two existing functions to use it.

This fixes vhost when IOMMU is disabled by guest.
