drm/panthor: Fix immediate ticking on a disabled tick

Browse source

[ Upstream commit 4356d21994 ]

We have a few paths where we schedule the tick work immediately without
changing the resched_target. If the tick was stopped, this would lead
to a remaining_jiffies that's always > 0, and it wouldn't force a full
tick in that case. Add extra checks to cover that case properly.

v2:
- Fix typo
- Simplify the code as suggested by Steve

v3:
- Collect R-b
