[Kimchi-devel] [PATCH 3/6] Check currentMemory exists prior to remote its XML node

[Aline Manera]

When updating the guest memory, the currentMemory node must be removed
to reflect the new value.
But it the guest was never started it does not have a currentMemory
node. So check it is exists first prior to remove it.
