drm/client: Use actual bpp when allocating frame buffers
When allocating a frame buffer, the number of bits per pixel needed is
derived from the deprecated drm_format_info.cpp[] field. While this may
work for formats using less than 8 bits per pixel, it does lead to a
large overallocation.
Reduce memory consumption by using the actual number of bits per pixel
instead.
