diff: restrict pathspec limitations to diff b/f case only
builtin_diff_b_f() needs a path, not pathspec. Other modes in diff can deal with pathspec just fine. But because of the current GUARD_PATHSPEC() location, other modes also reject :(glob) and :(icase). Move GUARD_PATHSPEC(), and the "path" assignment statement, which is the reason of this GUARD_PATHSPEC(), inside builtin_diff_b_f().
