[Pgpool-committers] pgpool - pgpool-II: Fix pool_get_node_info() so that it deals with

[User T-ishii]

Log Message:
-----------
Fix pool_get_node_info() so that it deals with node_number == -1 case.
This could happen get_next_master_node() returns -1 because
there's no master node available (all nodes down case).
Also tweak trigger_failover_command() to deal with pool_get_node_info()
returns NULL case.
Per report from Wouter D'Haeseleer.
