aacpsy: avoid psy_band->threshold becoming NaN

If band->thr is 0.0f, the division is undefined, making norm_fac not a
number or infinity, which causes psy_band->threshold to become NaN.

This is passed on to other variables until it finally reaches
sce->sf_idx and is converted to an integer (-2147483648).

This causes a segmentation fault when it is used as array index.
