[PATCH v5 02/18] ima: Remove some superfluous parentheses

[Thiago Jung Bauermann <bauerman@linux.vnet.ibm.com>]

Superfluous parentheses just add clutter to the code, making it harder to
read and to understand.

In order to avoid churn and minimize conflicts with other patches from the
community, this patch only removes superfluous parentheses from lines that
are modified by other patches in this series.

Confirmed that the patch is correct by comparing the object files from
before and after the patch. They are identical.
