msc: CC Re-Est: allow MNCC_RTP_CREATE upon Assgmt
In f_tc_call_re_establishment_2(), after Assignment Complete, optionally
allow an MNCC_RTP_CREATE.
When Re-Establishing a call, the Assignment Complete usually affects
codec and RTP address, so an MNCC_RTP_CREATE should happen after the
Assignment Complete message.
Current osmo-msc master does not send this MNCC_RTP_CREATE. This is
unlikely to be correct (would be ok if no RTP port changes), likely
omitted due to a bug.
An upcoming patch adds the MNCC_RTP_CREATE in Call Re-Establishment to
osmo-msc.
