OSBA MCT misconfiguration causes crashes at 256kbps

For OSBA modes, MCT misconfiguration during initialization causes crashes for modes coded with WB and SWB and 256kbps.

To reproduce one can use any file and code/decode it with 32kHz/16kHz

Example: Resample to 32kHz the wav file in https://forge.3gpp.org/rep/ivas-codec-pc/ivas-codec/-/wikis/uploads/1058c2733a89434b73423b64fb2d0538/15_Arboretum_Clean_Moving_4objs_oSBA_part1.7z

then ./IVAS_cod -ism_sba 4 1 15_Arboretum_Clean_Moving_4objs_o1.csv 15_Arboretum_Clean_Moving_4objs_o2.csv 15_Arboretum_Clean_Moving_4objs_o3.csv 15_Arboretum_Clean_Moving_4objs_o4.csv 256000 32 15_Arboretum_Clean_Moving_4objs_oSBA1_32kHz.wav bit
