[pgpool-committers: 4960] pgpool: Fix oversight in pool_extract_error_message().

[Tatsuo Ishii]

Fix oversight in pool_extract_error_message().

A variable used for storing the return value was mistakenly declared
as bool, rather than int.  This led to a segfault issue mentioned in
75b27e7 on certain platform.
