    growfs: do not error if filesystem is already requested size
    
    For some cloud/virtualization use cases it can be convenient to grow the
    filesystem on boot any time the disk/partition happens to be larger, but
    not fail if it remains the same size.
    
    Continue to emit a message if we have no action to take, but exit with
    status 0 if the size remains the same.
