[pgpool-committers: 3042] pgpool: Fix yet another reset query stuck problem

[Tatsuo Ishii]

Fix yet another reset query stuck problem

After receiving X message from frontend, if pgpool-II detects EOF on
the connection before sending reset query, pgpool-II could wait for
backend which had not received the reset query. To fix this, if EOF
received, treat this as FRONTEND_ERROR, rather than ERROR.

See "[pgpool-hackers: 1440] Yet another reset query stuck problem" for
more details.

Back patch to 3.5 stable tree as well (it seems 3.4 does not have the
problem as far as I tested it).
