drm/panthor: Reset queue slots if termination fails

Browse source

Make sure the queue slot is reset even if we failed termination so
we don't have garbage in the CS input interface after a reset. In
practice that's not a problem because we zero out all RW sections when
a hangs occurs, but it's safer to reset things manually, in case we
decide to not conditionally reload RW sections based on the type of
hang.

v4:
- Split the changes in two separate patches

v5:
- No changes

v6:
- Adjust the explanation in the commit message
- Drop the Fixes tag
- Put after the timeout changes and make the two patches independent
  so one can be backported, and the other not

v7:
- Use the local group variable instead of dereferencing csg_slot->group
- Add Steve's R-b

v8:
- No changes
