glx: Fix __glXWireToEvent for BufferSwapComplete
In the DRI2 path this event is magically synthesized from the corresponding DRI2 event, but with Present, the server sends us the event itself. The DRI2 path fills in the serial number, send_event, and display fields of the XEvent struct that the app sees, but the Present path did not. This is likely related to a class of crashes seen in gtk/clutter apps: https://bugzilla.redhat.com/attachment.cgi?id=1032631 Note that the crashing instruction is looking up the lock_fns slot in the Display *, and %rdi (holding the Display *) is 0x1.
