Wen Congyang 968fd0111a release PCI address only when we have ensured it successfully 
Steps to reproduce this bug:
1. # cat net.xml # 00:03.0 has been used
    <interface type='network'>
      <mac address='52:54:00:04:72:f3'/>
      <source network='default'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
    </interface>

2. # virsh attach-device vm1 net.xml
   error: Failed to attach device from net.xml
   error: internal error unable to reserve PCI address 0:0:3

3. # virsh attach-device vm1 net.xml
   error: Failed to attach device from net.xml
   error: internal error unable to execute QEMU command 'device_add': Device 'rtl8139' could not be initialized

The reason of this bug is that: we can not reserve PCI address 0:0:3 because it has
been used, but we release PCI address when we reserve it failed.

         LibVirt : simple API for virtualization

  Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
