[libvirt] [PATCH] qemu: reject min_guarantee at parse time

[Cole Robinson]

min_guarantee isn't implemented for qemu, and an explicit check was
added in june 2014 to reject the VM at qemu startup time. It's a weird
place to do XML validation, so move it to the post parse area where
we have similar checks.

Also drop a validation check against min_guarantee in the command line
building; it will never see min_guarantee there.
