drm/amd/display: Don't leak memory when updating streams

[Why]
The flip and full structures were allocated but never freed.

[How]
Free them at the end of the function. There's a small behavioral
change here with the function returning early if the allocation fails
but we wouldn't should be doing anything in that case anyway.

Fixes: c00e0cc0fdc0 ("drm/amd/display: Call into DC once per multiplane flip")
Fixes: ea39594e0855 ("drm/amd/display: Perform plane updates only when needed")
