msc: Fix random error of TC_cl3_rnd_payload
The random length for that test could go out of bounds leading to a Dynamic test case error when sending the message. The limiting field here is the lengthIndicator of PDU_BSSAP which includes the length of the PDU_BSSMAP mesageType, cellId as well as the layer3 info IE and lenght indicator additionally to the l3info payload. So maximum length for the payload can only be 240 bytes (if the cell ID is encoded in the longest possible way as BSSMAP_FIELD_LAC_RNC_CI). Change-Id: I7be33e261a11f03a80a6b770b6acf0a4be49b85b
