[pgpool-committers: 3967] pgpool: Fixing a mistake in the watchdog code.

[Muhammad Usama]

Fixing a mistake in the watchdog code.

wrong conditional statement in the get_wd_command_from_reply() function was
making the watchdog to not reliably identify the internal command responses,
and in one case the completed watchdog internal command were not getting
cleaned up.
commit also adds some debug messages in the watchdog code.
