mm/sharepool: Fix sharepool node id invalid when using sp_alloc

hulk inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I54IL8


CVE: NA

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

When passing numa id to sp_alloc, sometimes numa id does not work.
This is because memory policy will change numa id to a preferred one if
memory policy is set. Fix the error by mbind virtual address to desired
numa id.
