Fix infinit loop when stream_socket_client return false

[mykiwi]

Hi

I have an issue with the package. When my SSR server is down, my PHP app fails: Error: Maximum execution time of 30 seconds exceeded

If you don't check stream_socket_client, $sock could be equals to false.

while (!feof($sock)) { // while (true)

Nice @mykiwi , I already encountered the problem too, I have patched this locally for the moment, but would be nice to include it mainstream.
