Revert "Fix bug in checking of IDENTIFY_SYSTEM result."
This reverts commit 083d29c65b7897f90c70e6dc0a4240a5fa75c8f2.
The commit changed the code so that it causes an errors when
IDENTIFY_SYSTEM returns three columns. But which prevents us
from using the replication-related utilities against the server
with older version. This is not what we want. For that
compatibility, we allow the utilities to receive three columns
as the result of IDENTIFY_SYSTEM eventhough it actually returns
four columns in 9.4 or later.
