drm/client: Convert drm_client_buffer_addfb() to drm_mode_addfb2()

Currently drm_client_buffer_addfb() uses the legacy drm_mode_addfb(),
which uses bpp and depth to guess the wanted buffer format.
However, drm_client_buffer_addfb() already knows the exact buffer
format, so there is no need to convert back and forth between buffer
format and bpp/depth, and the function can just call drm_mode_addfb2()
directly instead.
