[pgpool-committers: 6968] pgpool: Fix error stats.

[Tatsuo Ishii]

Fix error stats.

Error stats was only collected from Master node. It is possible that
error occurred in multiple backends (for example, in native
replication mode, INSERT is accepted by the parser but target table
does not exist).  Change the place where to collect error stats from
SimpleForwardToFrontend() to read_kind_from_backend().
