[pgpool-committers: 3364] pgpool: Fixing a coding mistake in watchdog code.

[Muhammad Usama]

Fixing a coding mistake in watchdog code.

wd_issue_failover_lock_command() function is supposed to forward command type
passed in as an argument to the wd_send_failover_sync_command() function instead
it was passing the NODE_FAILBACK_CMD command type.
The mistake was caught by uehara

The commit also contains some log message enhancements
