Unable to set read buffer on tcp socket in socket_listener

[danielnelson]

Bug report

Relevant telegraf.conf:

[[inputs.socket_listener]]
  service_address = "tcp://:8094"
  read_buffer_size = 65535

System info:

Telegraf 1.5.2

Steps to reproduce:

1. Enable socket_listener as described above
2. Start Telegraf

Expected behavior:

Read buffer size set

Actual behavior:

2018-03-09T01:37:59Z W! Unable to set read buffer on a tcp socket

@phemmer I'm confused how this code works, it looks like we are attempting to call SetReadBuffer on a Listener type, which would never have this function, instead of on a Conn type.

You're right. Oops. I have no idea what I was thinking when I wrote that. That should be moved to after the accept.

[phemmer]

Trivial fix. You want me to do it, or are you getting it?

[danielnelson]

I'm always willing to let someone else do my work :)

Well I kinda feel like I should clean up my own mess, so I'll do it now. Have a PR up in a few :-)
