Fixes stv crash issue due to Assertion issue caused by L_shl in sub function of hq_core_dec_fx() 

[x] The crash occurs due to assertion issue
caused by L_shl for values just above 0.5 in Q27
when left shifted by 5, which was not handled in
the EVS implemented hq_generic_decoding_fx().
The order of multiply and left shift was altered
with which issue was resolved. If issue occurs
again, copy of hq_bwe_fx and hq_generic_decoding_fx
for IVAS needs to be created.
