net: tcp: prepare_segment: Return detailed error codes. prepare_segment() returned NULL in case of any error, which then net_context_send() translated into -EINVAL. That's highly confusing though, because a common case of failure for prepare_segment() is being unable to allocate data fragment(s) (for TCP header, etc.) So, return output pkt by reference, and detailed error status as a return value.
