mm/damon: fix missing parens in macro arguments

Patch series "mm/damon: fix macro arguments and clarify quota goals doc",
v2.

This patch (of 2):

The DAMON iterator macros do not wrap their pointer arguments with
parentheses.  This can cause build failures when the argument is a complex
expression due to operator precedence issues.

Add missing parentheses around the arguments in the following macros
to prevent potential build failures:
- damon_for_each_region()
- damon_for_each_region_from()
- damon_for_each_region_safe()
- damos_for_each_quota_goal()
