Revert "LXC: show used memory as 0 when domain is not active"
This reverts commit 1ce7c1d20cfd5afb26d2dbc88201085d52415d0e,
which introduced a significant semantic change to the
virDomainGetInfo() API. Additionally, the change was only
made to 2 of the 15 virt drivers.

Description of problem: The vaule of Used memory in 'virsh dominfo' is 0 when the guest is shut off Version-Release number of selected component (if applicable): kernel-3.10.0-322.el7.x86_64 qemu-kvm-1.5.3-104.el7.x86_64 libvirt-1.2.17-13.el7.x86_64 How reproducible: 100% Steps to Reproduce: 1. create a guest named rhel7 2. #virsh destroy rhel7 3. #virsh dumpxml rhel7 ******* <memory unit='KiB'>4194300</memory> <currentMemory unit='KiB'>1024857</currentMemory> ******* 4. #virsh dominfo rhel7 ******* Max memory: 4194300 KiB Used memory: 0 KiB ******* Actual results: the vaule of Used memory in step4 is 0,that is not the same as the value of currentMemory in step 3 Expected results: the vaule of Used memory in step4 is the same as the value of currentMemory in step 3
