suspend/resume -- such PGDs are completely empty and so
contain no PTEs that become garbage across suspend/resume.

To perform this check in the same transaction as the writing of the device
entries has required a little bit of rejigging.

Callers no need to check log-dirty status themselves.
Also, add dirty logging to alloc_page_type/free_page_type, so
that we see page tables coming and going during live relocation.

emerged as a problem in the field, AFAIK, but it seems that distro scripts
could have brought the device down already by this point (Debian stable's
net.agent does ifdown vifX.Y, and it wouldn't surprise me if someone decided
to do ifconfig vifX.Y down if this failed, for example).
Logging but ignoring the failure seems sensible.
