[PATCH] builtin/grep.c: remote superflous submodule code

In f9ee2fcdfa (grep: recurse in-process using 'struct repository',
2017-08-02), we introduced a call to repo_read_gitmodules in builtin/grep
to simplify the submodule handling.

After ff6f1f564c4 (submodule-config: lazy-load a repository's .gitmodules
file, 2017-08-03) this is no longer necessary, but that commit did not
cleanup the whole tree, but just show cased the new way how to deal with
submodules in ls-files.

It claimed that grep would still need some explicit handling, but that is
not the call to repo_read_gitmodules (applying this patch on top of
ff6f1f564c4 still keep the test suite happy, specifically
t7814-grep-recurse-submodules, which contains a test
"grep history with moved submoules")

The special handling is the call to gitmodules_config_oid which was added
already in 74ed43711f (grep: enable recurse-submodules to work on
<tree> objects, 2016-12-16), but then was still named

This is a resend of origin/sb/grep-submodule-cleanup,
and I think picking ff6f1f564c4 as the base for the series would
also be appropriate.
