This command is probably the first one that operates on a repository
other than the_repository, in f9ee2fcdfa (grep: recurse in-process
using 'struct repository' - 2017-08-02). An explicit 'struct
repository *' was added in that commit to pass around the repository
that we're supposed to grep from.
Since 38bbc2ea39 (grep.c: remove implicit dependency on the_index -
2018-09-21). 'struct grep_opt *' carries in itself a repository
parameter for grepping. We should now be able to reuse grep_opt to
hold the submodule repo instead of a separate argument, which is just
room for mistakes.
While at there, use the right reference instead of the_repository and
the_index in this code. I was a bit careless in my attempt to kick
the_repository / the_index out of library code. It's normally safe to
just stick the_repository / the_index in bultin/ code, but it's not
the case for grep.
