bitbake: process: Reorder server command processing and handle EOFError
If the connection control socket and the command channel close together, we can race and hit EOFError exceptions before we close the channel. Reorder the code to handle this in the correct order and ignore the EOFError exceptions as they mean the client is disconnecting and shouldn't terminate the server. (Bitbake rev: 974281ed72d8366baa16ee85f7e93970689b5956) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
