[pgpool-committers: 4194] pgpool: Fix ancient bug of pool_unread.

[Tatsuo Ishii]

Fix ancient bug of pool_unread.

When realloc() is called in pool_unread(), it did not update the
buffer size.  This could cause variety of memory corruption and
unexpected data reading from backend. The reason why we did not found
that is, probably recently Pgpool-II starts extensively to use
pool_unread().
