[PATCH v2 4/6] grep: remove redundant and verbose re-assignments to 0

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

Remove the redundant re-assignments of the fixed/pcre1/pcre2 fields to
zero right after the entire struct has been set to zero via
memset(...).

See an earlier related cleanup commit e0b9f8ae09 ("grep: remove
redundant regflags assignments", 2017-05-25) for an explanation of why
the code was structured like this to begin with.
