    Set bitmap size when allocating a bitmap
    
    I began noticing a race when reserving VNC ports as described here
    
    https://www.redhat.com/archives/libvir-list/2010-November/msg00379.html
    
    Turns out that we were not initializing the size field of bitmap
    struct when allocating the bitmap.  This subsequently caused
    virBitmapSetBit() to fail since bitmap->size is 0, hence we never
    actually reserved the port.
