BUG/MINOR: server: Be really able to keep "pool-max-conn" idle connections

Browse Source 
The maximum number of idle connections for a server can be configured by setting
the server option "pool-max-conn". But when we try to add a connection in its
idle list, because of a wrong comparison, it may be rejected because there are
already "pool-max-conn - 1" idle connections.

This patch must be backported to 2.0 and 1.9.
