Revert "libobs: Correctly set texture size"

This reverts commit 90a409fe586daf7b3430ea3be9581efc93998cc1.

Reverts #7077 for now. This really shouldn't be done so close to
release. This crash technically only happens under very niche scenarios,
and the fix seems to have some other potential issues. Prematurely
merged by Jim.
