[pgpool-committers: 5590] pgpool: Fix compiler warnings.

[Tatsuo Ishii]

Fix compiler warnings.

To deal with compiler warnings regarding that the return value of
write(2) is ignored, replace it with write_it() which calls write()
and uses the return value from it to print error string when write()
returns error.
