net: fix inconsistent error values on setters
This change fixes inconsistent error values on Set{Deadline,ReadDeadline,WriteDeadline,ReadBuffer,WriteBuffer} for Conn, Listener and PacketConn, and Set{KeepAlive,KeepAlivePeriod,Linger,NoDelay} for TCPConn. Updates #4856. Change-Id: I34ca5e98f6de72863f85b2527478b20d8d5394dd Reviewed-on: https://go-review.googlesource.com/9109 Reviewed-by: Ian Lance Taylor <iant@golang.org>
