[pgpool-committers: 4844] pgpool: Fix "write on backend 0 failed with error :"Success"" error.

[Tatsuo Ishii]

Fix "write on backend 0 failed with error :"Success"" error.

While writing to a socket, sometimes write() returns 0. Before we
treated this as an error, but it seems this could happen in the field
and is better to be treated as normal. So if write() returns 0, then
retry write() instead of raise an error.

Per bug #403.
