Remove the redundant re-assignment of the fixed field to zero right
after the entire struct has been set to zero via memset(...).

Unlike some nearby commits this pattern doesn't date back to the
pattern described in e0b9f8ae09 ("grep: remove redundant regflags
assignments", 2017-05-25), instead it was apparently cargo-culted in
9eceddeec6 ("Use kwset in grep", 2011-08-21).
