msc-test: improve error log on Assignment RTP port mismatch

Before this, if an Assignment Request contains an unexpected Transport Layer
Address, the test completely rejects the Assignment Request.

Instead, accept any tla in the Assignment, and compare the expected tla in the
Assignment's interleave action. Thus we directly get logging hinting at the tla
instead of a T_guard timeout.
