qemuDomainDetachDiskDevice() is only called from one place. Moving the
contents of the function to that place makes
qemuDomainDetachDiskLive() more similar to the other Detach functions
called by the toplevel qemuDomainDetachDevice().
The goal is to make each of the device-type-specific functions do this:
1) find the exact device
2) do any device-specific validation
3) do general validation
4) do device-specific shutdown (only needed for net devices)
5) do the common block of code to send device_del to qemu, then
optionally wait for a corresponding DEVICE_DELETED event from
qemu.
with the final aim being that only items 1 & 2 will remain in each
device-type-specific function, while 3 & 5 (which are the same for
almost every type) will be de-duplicated and moved to the toplevel
function that calls all of these (qemuDomainDetachDeviceLive(), which
will also contain a callout to the one instance of (4) (netdev).
I'm not sure whether this is worth setting into ston^w commit message.
Yeah, that should go below the --, but I can never remember to do that
when sending the patch, so I just include the comments in the commit
message and remove it later. (Is there a way to add "meta comments"?)

Ooh!! Good eye!!
ACK with the above fixed.
