Subject: [PATCH 2/2] mm/damon/Kconfig: Remove unnecessary PAGE_EXTENSION setup

Commit 13d49dbd0123 ("mm/damon: implement primitives for the virtual
memory address spaces") of linux-mm[1] makes DAMON_VADDR to set
PAGE_IDLE_FLAG.  PAGE_IDLE_FLAG sets PAGE_EXTENSION if !64BIT.  However,
DAMON_VADDR do the same work again.  This commit removes the unnecessary
duplicate.
