[PATCH 10/19 5.15.y] minmax: don't use max() in situations that want a C constant expression

[Eliav Farber <farbere@amazon.com>]

From: Linus Torvalds <torvalds@linux-foundation.org>

[ Upstream commit cb04e8b1d2f24c4c2c92f7b7529031fc35a16fed ]

We only had a couple of array[] declarations, and changing them to just
use 'MAX()' instead of 'max()' fixes the issue.

This will allow us to simplify our min/max macros enormously, since they
can now unconditionally use temporary variables to avoid using the
argument values multiple times.
