[v3,01/13] mac_newworld: Drop some variables

Commit Message

BALATON Zoltan Oct. 3, 2022, 8:13 p.m. UTC

Values not used frequently enough may not worth putting in a local
variable, especially with names almost as long as the original value
because that does not improve readability, to the contrary it makes it
harder to see what value is used. Drop a few such variables. This is
the same clean up that was done for mac_oldworld in commit b8df32555ce5.
