[pgpool-committers: 1881] pgpool: Fix query cache is enabled and protocol version = 2 case.

[Muhammad Usama]

Fix query cache is enabled and protocol version = 2 case.

When the protocol version = 2, we assume that session state is "idle".
This is not feasible but no way. I recommend to not use query cache
with protocol 2.
Per Coverity report 1111488 "Uninitialized scalar variable".
