drm/amd/display: Don't check for NULL divisor in fixpt code
[Why]
We check for a NULL divisor but don't act on it.
This check does nothing other than throw a warning.
It does confuse static checkers though:
See https://lkml.org/lkml/2025/4/26/371
[How]
Drop the ASSERTs in both DC and SPL variants.

Fixes: 6efc0ab3b05d ("drm/amd/display: add back quality EASF and ISHARP and dc dependency changes")
