Well, the last listing is just an AP that your client was once associated to, but has since left to join the new one. I can't explain the all-zeros MAC address, so maybe someone else can chime in there. It's clearly not an accurate piece of info, and it's likely some bit of data that resulted out of your last roam.
As Jeff mentioned, this is due to your client roaming and most likely due to wlc roaming. The information you see is not real time accurate, especially the wlc information of clients. You can see that 10.92.0.111 shows the client as still being authenticated which is not the case. So most likely what happens is the wlc is cached until flushed or cleared, but ap's keep the real time information, so the all zero's just mean that the wlc knows of the client but not yet flushed the old info and when it tries to detect which ap that user is on, there isn't one.... so it produces the all zero's.
