Assert in StereoDmxEVS complexity job in EVS decoder

Basic info

• Fixed point: a8d5672d

Bug description

Some modes in the StereoDmxEVS complexity run trigger an assert in the decoder. The decoder is pure EVS.

IVAS_dec: lib_com/fd_cng_com_fx.c:1234: minimum_statistics: Assertion `msNoiseEst[j] >= 0' failed.

Ways to reproduce

⚠️ Could not reproduce this, neither in the runner container, nor locally on my Laptop ⚠️
