dmop: Add XEN_DMOP_nr_vcpus
Curiously absent from the stable API/ABIs is an ability to query the number of
vcpus which a domain has. Emulators need to know this information in
particular to know how many stuct ioreq's live in the ioreq server mappings.
In practice, this forces all userspace to link against libxenctrl to use
xc_domain_getinfo(), which rather defeats the purpose of the stable libraries.
Introduce a DMOP to retrieve this information and surface it in
libxendevicemodel to help emulators shed their use of unstable interfaces.

For 4.15. This was a surprise discovery in the massive ABI untangling effort
I'm currently doing for XenServer's new build system.
This is one new read-only op to obtain information which isn't otherwise
available under a stable API/ABI. As such, its risk for 4.15 is very low,
with a very real quality-of-life improvement for downstreams.
I realise this is technically a new feature and we're long past feature
freeze, but I'm hoping that "really lets some emulators move off the unstable
libraries" is sufficiently convincing argument.
It's not sufficient to let Qemu move off unstable libraries yet - at a
minimum, the add_to_phymap hypercalls need stabilising to support PCI
Passthrough and BAR remapping.
I'd prefer not to duplicate the op handling between ARM and x86, and if this
weren't a release window, I'd submit a prereq patch to dedup the common dmop
handling. That can wait to 4.16 at this point. Also, this op ought to work
against x86 PV guests, but fixing that up will also need this rearrangement
into common code, so needs to wait.

x86/dmop: Properly fail for PV guests
The current code has an early exit for PV guests, but it returns 0 having done
nothing.

Well - there's only one possibility here...

Or it's the heisenbug, and the next flight is going to be fine.
I've not spotted anything unusual in the logs so far.
