add error checker when creating cmd queue in client: especially when OoO queue is not supported on many devices

[tingxingdong]

By default , the client created a out-of-orer queue. However, most devices only support in-order queue. The main purpose of client is to test clBLAS maths functions not test queues. It is better to change into in-order queue by default.

An error checker should be inserted, even certain property queue is not supported, error can be caught much earlier.
