Earlier commit 157b34af65168 ("tests/intel/xe_eu_stall: Use default sampling rate
from the query IOCTL data") used a mid sampling rate from those returned
from the query IOCTL, if the user doesn't pass a sampling rate. However, some
GPUs, sometimes, aren't generating any EU stall data with the mid sampling
rate with 100 iterations of GPGPU fill. So, Use the fastest sampling rate
from the query IOCTL data so that there is always some EU stall data
generated with GPGPU fill.
