Redo range check in CPDF_SampledFunc::v_Call().
The current |bitpos1| calculation protects the passed argument to
_GetBits32(): |bitpos.ValueOrDie() + j * m_nBitsPerSample|, but doesn't
account for adding in the sample length in that routine.
Also bound bits per sample to something reasonable to avoid undefined
behaviour on the shift to compute the max value.
