[SYCL] Unsupported kernel parameter type

[jinz2014]

Building the sycl benchmark at (https://github.com/bcosenza/sycl-bench) causes the following error after I build the current SYCL. Thanks for your check.

@jinz2014, the application seems to capture array, which is not supported yet.
This is supposed to be fixed by #1423.
You can also put this array into SYCL buffer to fix this problem.

[jinz2014]

I will close the issue after it is supported. Thanks again.
