The 'swtich-case' statement in 'damon_va_apply_scheme()' function
provides a 'case' for every supported DAMOS action while all
not-yet-supported DAMOS actions fall through the 'default' case, and
comment it so that people can easily know which actions are supported.
Its counterpart in 'paddr', 'damon_pa_apply_scheme()', however, doesn't.
This commit makes the 'paddr' side function follows the pattern of
'vaddr' for better readability and consistency.
