check_rtp_origin: drop special case for legacy IuUP hack

We have proper IuUP support and everything about this legacy hack should
be purged.

The purpose of this function is to validate that RTP is coming from the
expected address and port. To allow that legacy IuUP hack, which is no
longer needed, we punched a hole into this validation, by adding this
special case for loopback mode (suddenly we don't care who or what sends
RTP and bounce it back to anyone). So let's get rid of this hole that
was only needed for very early 3G voice hacking.

Instead, we permit RTP for IuUP Initialization regardless of the RTP
loopback/send/recv mode since I6c365559a7bd197349f0ea99f7a13b56a4bb580b
