Subject: [PATCH] qemuDomainDeviceDefValidateNetwork: Check for range only if
IP prefix set
https://bugzilla.redhat.com/show_bug.cgi?id=1515533
The @prefix attribute to <ip/> element for interface type user is
optional. Therefore, if left out it has value of zero in which
case we should not check whether it falls into <4, 27> range.
Otherwise we fail parsing domain XML for no good reason.
Broken by commit b62b8090b2ad4524a5bf9d40d0d1c17a9d57f5a0.
