share_pool: Rename buff_vzalloc_user and buff_vzalloc_hugepage_user

ascend inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I4EUVI
CVE: NA

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

Let function names be general.
Rename buff_vzalloc_user to vzalloc_user_account.
Rename buff_vzalloc_hugepage_user to vzalloc_hugepage_user_account.

To support NUMA configuration, we also introduce parameter *node*,
which means NUMA node id.
