patch 8.2.1898: command modifier parsing always uses global cmdmod

Commit: https://github.com/vim/vim/commit/e10044015841711b989f9a898d427bcc1fdb4c32
Author: Bram Moolenaar <Bram@vim.org>
Date:   Sat Oct 24 20:49:43 2020 +0200

    patch 8.2.1898: command modifier parsing always uses global cmdmod

    Problem:    Command modifier parsing always uses global cmdmod.
    Solution:   Pass in cmdmod_T to use.  Rename struct fields consistently.
