[IPVS]: use proper timeout instead of fixed value

Instead of using the default timeout of 3 minutes, this uses the timeout
specific to the protocol used for the connection. The 3 minute timeout
seems somewhat arbitrary (though I know it is used other places in the
ipvs code) and when failing over it would be much nicer to use one of
the configured timeout values.
