[libvirt] [PATCH] domMemoryStats / qemu: Fix parsing of unknown stats

Fix a small problem with the qemu memory stats parsing algorithm. If qemu reports a stat that libvirt does not recognize, skip past it so parsing can continue. This corrects a potential infinite loop in the parsing code that can only be triggered if new statistics are added to qemu.
