Check validity of color indices in bmp_decode_rgb
The pal_num member of bmp_ptr indicates the number of color indices
used by the bitmap. This CL returns an error when an invalid index is
found, since otherwise a heap-buffer-overflow can occur since the size
of m_pSrcPalette is calculated based on pal_num.
