This patch removes unnecessary parentheses from all EVM and IMA files touched by this patch series. The difference from the previous patch is that it cleans up the files as a whole, not just the lines that were already going to be modified by other patches. It is separate from the previous one so that it can be easily dropped if the churn and conflict potential is deemed not worth it. Confirmed that the patch is correct by comparing the object files from before and after the patch. They are identical.
