Description

bssmap_rx_ciph_rej() looks for a cause IE using the BSS_MAP_MSG_CIPHER_MODE_REJECT message discriminator. This is clearly wrong and invariably leads to

<000a> a_iface_bssap.c:629 Rx MSC DT1 BSSMAP CIPHER MODE REJECT
<000a> a_iface_bssap.c:453 BSC sends cipher mode reject (conn_id=65)
<000a> a_iface_bssap.c:457 Cause code is missing -- discarding message!

We need a test verifying that the MSC properly receives a Cipher Mode Reject.
Since in ttcn3, we don't verify log output, this might actually be good to incorporate in the msc_vlr tests instead?
Is there a message response we could trigger on in ttcn3?
