    Initialize event type
    
    If we receive unsupported event closing connection triggers valgrind
    error.
    
    ==12017== Conditional jump or move depends on uninitialised value(s)
    ==12017==    at 0x487D454: _XFreeDisplayStructure (OpenDis.c:607)
    ==12017==    by 0x486857B: XCloseDisplay (ClDisplay.c:72)
    *snip*
    ==12017==  Uninitialised value was created by a heap allocation
    ==12017==    at 0x4834C48: malloc (vg_replace_malloc.c:236)
    ==12017==    by 0x4894147: _XEnq (XlibInt.c:877)
    ==12017==    by 0x4891BF3: handle_response (xcb_io.c:335)
    ==12017==    by 0x4892263: _XReply (xcb_io.c:626)
    *snip*
    
    Problem is that XFreeDisplaySturture is checking for qelt->event.type ==
    GenericEvent while _XUnknownWireEvent doesn't store the type.
