lib: drive_create_data, drive: remove field "iface"

Browse Source 
Representing "iface" in the "drive_create_data" and "drive" structures is
now useless; the direct backend ignores "iface", while the libvirt one
rejects it unless it is empty. Unify both backends -- make them both
ignore "iface". (Which only relaxes the libvirt backend, so it cannot
cause compatibility problems.) This lets us remove the fields. Update the
documentation as well.
