drm/xe/throttle: Skip reason prefix while emitting array 

The newly introduced "reasons" attribute already signifies possible
reasons for throttling and makes the prefix in individual attribute
names redundant while emitting them as an array. Skip the prefix.

Fixes: 83ccde67a3 ("drm/xe/gt_throttle: Avoid TOCTOU when monitoring reasons")
