Re: [libvirt] [PATCH 07/21] qemu_hotplug: refactor qemuDomainDetachDiskLive and qemuDomainDetachDiskDevice

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).
