mm/dynamic_pool: Stop alloc reliable page from dynamic pool 

hulk inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I9CDZZ



--------------------------------

With memory reliable enabled, user expect to alloc memory from mirrored
regions (also known as the non-movable zone). However dynamic pool does
not contain such reliable information. So bypass it.
