[pgpool-committers: 7989] pgpool: Fix pgpool logger process eats 100% cpu.

[Tatsuo Ishii]

Fix pgpool logger process eats 100% cpu.

The select(2) loop in the logger process did not initialize
timeout.tv_usec, which could cause error in select(2) because of too
big tv_usec. In this select(2) immediately returned and iterate the
for loop.

Problem reported and patch provided by Fang Jun.
