3796bb0048 Revert "s3/service: convert lp_force_group() to const"
This reverts commit c53646bccd.
As mentioned by Andrew, we shouldn't break environments where
"force group" has been configured to use substituted variables.

0a91ade527 s3: smbd/durable: remove dev and inode check from vfs_default_durable_reconnect_check_stat()
On a cluster filesystem the device numbers may differ on the cluster
nodes. We already verify the file_id in vfs_default_durable_reconnect(),
so we can safely remove the dev/inode checks.

4ad2a716fb s3: smbd: fix a check in stat_cache_add()
As the comment above the if condition says:

        /*
         * If we are in case insentive mode, we don't need to
         * store names that need no translation - else, it
         * would be a waste.
         */

Ie if stat_cache_add() is called as

        stat_cache_add("foo/bar", "foo/bar", false)

There's no need to cache the path, as a simple stat() on the client
supplied name (full_orig_name) matches the name used in the
filesystem (passed to stat_cache_add() as translated_path).

So fix the if condition to match the comment.

These are the two opcodes with DO_CHDIR, we don't want the
set_current_case_sensitive() logic for them,
so we don't need the full set_current_service() anymore.

The AS_USER case is already handled before, set_current_case_sensitive()
is called directly before change_to_user(), which already
calls chdir_current_service().
