Increase maximum number of zeromq sockets and improve output on errors.

FairMQSampler: Modified: comment out an unused loop.
FairMQ: Modified: increase maximum number of ZeroMQ sockets (from default 1024).
FairMQ: Modified: reduce amount of output when finding port from a range.
FairMQ: Modified: stop the Device when socket creation fails and output an error.
