drm/xe: Cancel pending TLB inval workers on teardown

Browse source

[ Upstream commit 76186a253a ]

Add a new _fini() routine on the GT TLB invalidation
side to handle this worker cleanup on driver teardown.

v2: Move the TLB teardown to the gt fini() routine called during
    gt_init rather than in gt_alloc. This way the GT structure stays
    alive for while we reset the TLB state.
