drm/amd/display: Fix writeback format loop and variable init

Browse source

[WHAT]
1. Use ARRAY_SIZE() instead of manual sizeof division for the
   format array iteration. Add a break statement to exit the loop
   early once a matching format is found.
2. Remove redundant zero initialization of res since all paths
   assign before use.
