[PATCH 4/5] drm/xe: Rename EXEC_MODE_LR to EXEC_MODE_FAULT in hw engine group

["Thomas Hellström" <thomas.hellstrom@linux.intel.com>]

The execution mode tracked by xe_hw_engine_group_execution_mode
describes whether the hw engine group is currently executing jobs
in fault mode (long-running, fault-capable) or in DMA fence mode.
The EXEC_MODE_LR label was misleading since not all LR queues use
fault mode; rename it to EXEC_MODE_FAULT for clarity.

No functional change.
