[PATCH] drm/xe: Do not wedge device on killed exec queues

[Matthew Brost]

When a user closes an exec queue or interrupts an app with Ctrl-C,
this does not warrant wedging the device in mode 2.

Avoid this by skipping the wedge check for killed exec queues in
the TDR and LR exec queue cleanup worker.
