The message seems to be coming from here:

source4/dsdb/samdb/ldb_modules/schema_load.c [line 218]

	if (schema != NULL) {
		if (ret == LDB_SUCCESS) {
			if (schema->metadata_usn == schema_seq_num) {
				TALLOC_FREE(mem_ctx);
				return schema;
			} else {
				DEBUG(3, ("Schema refresh needed %lld != %lld\n",
					  (unsigned long long)schema->metadata_usn,
					  (unsigned long long)schema_seq_num));
			}
		} else {


I wouldn't use Samba from git in production, I would use the latest
available tarball.
If everything is working okay, you could use 'log level = 2' in
smb.conf, this should turn off the messages. It wont fix the problem
though, which seems to be a problem with the schema.
