domMemoryStats / qemu: Fix parsing of unknown stats

Browse Source 
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.

* src/qemu/qemu_monitor_text.c: qemuMonitorParseExtraBalloonInfo add a
  skip for extra ','
