Ladi Prosek 4eae2a657d balloon: fix segfault and harden the stats queue ... The segfault here is triggered by the driver notifying the stats queue twice after adding a buffer to it. This effectively resets stats_vq_elem back to NULL and QEMU crashes on the next stats timer tick in balloon_stats_poll_cb. This is a regression introduced in 51b19ebe43, although admittedly the device assumed too much about the stats queue protocol even before that commit. This commit adds a few more checks and ensures that the one stats buffer gets deallocated on device reset.
