conn: ensure control message size is respected in StdNetBind
This commit re-slices received control messages in StdNetBind to the
value the OS reports on a successful read. Previously, the len of this
slice would always be srcControlSize, which could result in control
message values leaking through a sync.Pool round trip. This is
unlikely with the IP_PKTINFO socket option set successfully, but
should be guarded against.
