Propagating errors to dependent fences is broken and can lead to
errors from one client ending up in another. In 3761baae908a (Revert
"drm/i915: Propagate errors on awaiting already signaled fences"), we
attempted to get rid of fence error propagation but missed the case
entation for new GuC interface")

Prior to this patch the blocked context counter was cleared on
init_sched_state (used during registering a context & resets) which is
incorrect. This state needs to be persistent or the counter can read the
incorrect value resulting in scheduling never getting enabled again.

we can postpone the start of the session to the first submission that
requires it, to avoid keeping it running with no user.
