If st_GetTexImage() is to decompress the texture, avoid the fallback path even if prefer_blit_based_texture_transfer = false. For drivers that returned PIPE_CAP_PREFER_BLIT_BASED_TEXTURE_TRANSFER = 0, we were always taking the fallback path for texture decompression rather than rendering a quad. The later is a lot faster.
