revision: use die_for_incompatible_opt3() for - -graph/--reverse/--walk-reflogs

The revision option --reverse is incompatible with --walk-reflogs and --graph is incompatible with both --reverse and --walk-reflogs. So they are all incompatible with each other. Use the function for checking three mutually incompatible options, die_for_incompatible_opt3(), to perform this check in one place and without repetition. This is shorter and clearer.
