drm/panthor: Fail job creation when the group is dead 



Userspace can use GROUP_SUBMIT errors as a trigger to check the group
state and recreate the group if it became unusable. Make sure we
report an error when the group became unusable.

Changes in v3:
- None

Changes in v2:
- Add R-bs

Fixes: de854881 ("drm/panthor: Add the scheduler logical block")
