[libvirt] [PATCH] virt drivers: show used memory as 0 when domain is inactive

Commit 1ce7c1d2 changed domainGetInfo to set virDomainInfoPtr->memory
to 0 when domain is inactive, but only did this for the LXC and QEMU
drivers. Make a similar change to the other virt drivers so they all
behave the same.

FYI, commit 1ce7c1d2 also broke libvirt-tck 110-memory-balloon.t test
not ok 13 - Get current memory is 924288
Failed test 'Get current memory is 924288'
at /usr/share/libvirt-tck/tests/domain/110-memory-balloon.t line 120.
got: '0'
expected: '924288'
A patch to fix the TCK test has been added to my TODO list.
