Variable Speed Decoding broken

Basic info

• Commit SHA: main
• Platform: all

Bug description

Variable Speed Decoding is not working as intended (i.e. going through the JBM path with just TSM), but goes through the default decoding path instead due to a wrong sanity check in https://forge.3gpp.org/rep/ivas-codec-pc/ivas-codec/-/blob/main/apps/decoder.c#L1579

Ways to reproduce

(Clear steps or refer to a failing automated test, e.g. with a pipeline link)
