* Encoder (float): 311956f3 (same with d705aad41)

* Decoder (float in both cases): 311956f3 (same with d705aad41)
# Bug description
When using -force HQ, the encoder sometimes crashes because of a uninitialized variable (no problem encounter in float)
It looks like the variables st->hHQ_core->crest_lp_q and st->hHQ_core->crest_mod_lp_q are not properly initialized if the codec starts in HQ mode.

# Ways to reproduce

IVAS_cod_fx -force HQ -ISM 1 NULL 24400 48 G4S5.wav bit
