I added code and commented out a faulty assertion to handle a mysterious crash that resulted from disconnecting devices from a macOS client. I had several crash reports that share this backtrace, and I finally reproduced it while connected to Xcode and found that buffer_size == 0 and done == true when a device disconnects. We get into this block of code where assert(buffer_size == sizeof(ref_upacket.size)), and the macOS client crashes. This assertion doesn't seem necessary. If there's no data and no error and GCD says we're done, then this is really just a no-op, and we should just return from the block rather than crash.
