Remove redundant condition check in 32x32 quant
Remove redundant condition check in 32x32 quant

The c code implementation of 32x32 quantization does the zbin check
of all coefficients prior to the quant/dequant loop, hence removing
the redundant zbin check inside the loop. This only affects the
c code version. SSSE3 version does not separate the zbin check out.
