I came across this when performing unaligned 8-byte writes on
x86_64-softmmu. The write was aligned to 4 bytes but not 8, so the
first 4 bytes were written just fine by
address_space_translate_cached(), but flatview_write_continue() failed
to write the following 4 bytes as it was translating the wrong
address. I'll mention this in the commit description.

Thanks,
Alberto
