xdiff: drop unused mmfile parameters from xdl_do_histogram_diff() 

These are no longer used since 9df0fc3d57 (xdiff: fix a memory leak,
2022-02-16), as the caller is expected to call xdl_prepare_env() itself.
After that change the histogram code only examines the prepared
xdfenv_t, not the original buffers.
