Log:
Clean up upon error when generating cs from argument count

Previously, using \cs_generate_from_arg_count:NNnn with a
number of arguments outside of [0,9] would leave the fourth
argument of \cs_generate_from_arg_count:NNnn in the input
stream after producing an error.  \use_none:n avoids that.
