Memory leak in MC Paramupmix with bitrate switching

Confirmed on 08510066 and also on 0fc9528d (older).

Steps to reproduce:

#!/bin/bash
git clone -b longer-testv-on-runners --single-branch https://forge.3gpp.org/rep/ivas-codec-pc/ivas-pc-testfiles.git
cp ivas-pc-testfiles/* scripts/testv/ # optional
make -j CLANG=2 # or use normally compiled binaries with valgrind (see below)
./IVAS_cod -mc 7_1_4 scripts/switchPaths/sw_24k4_256k.bin 48 scripts/testv/ltv48_MC714.wav mc.192
./IVAS_dec -FEC 5 STEREO 32 mc.192 /dev/null
