[PATCH 07/27] Revert "drm/i915/gt: Propagate change in error status to children on unhold"

[Matthew Brost]

Propagating errors to dependent fences is wrong, don't do it. A selftest
in the following exposed the propagating of an error to a dependent
fence after an engine reset.

This reverts commit 8e9f84cf5cac248a1c6a5daa4942879c8b765058.

v2:
 (Daniel Vetter)
