[PATCH] tests/intel/xe_sysfs_scheduler: fix save/restore array indexing

[nishit.sharma@intel.com]

From: Nishit Sharma <nishit.sharma@intel.com>

The scheduler property save/restore array was declared as
store[MAX_GTS][3][3] but indexed with the per-GT engine index in the
first (GT) dimension:

This drops the GT dimension completely: on multi-GT systems every GT
overwrites the same slots, so teardown restores each engine's
preempt_timeout/timeslice_duration/job_timeout with values from the
last GT that was saved, tripping the "not restored!" abort. It also
overflows the array whenever a GT exposes more than MAX_GTS engines.
