ConnectionExists: respect the max_concurrent_streams limits

Browse source 
A regression made the code use 'multiplexed' as a boolean instead of the
counter it is intended to be. This made curl try to "over-populate"
connections with new streams.

This regression came with 41fcdf71a1, shipped in curl 7.65.0.

Also, respect the CURLMOPT_MAX_CONCURRENT_STREAMS value in the same
check.
