[patch 166/173] hugetlbfs: use helper macro default_hstate in init_hugetlbfs_fs

From: Miaohe Lin <linmiaohe@huawei.com>
Subject: hugetlbfs: use helper macro default_hstate in init_hugetlbfs_fs

Since commit e5ff215941d5 ("hugetlb: multiple hstates for multiple page
sizes"), we can use macro default_hstate to get the struct hstate which we
use by default.  But init_hugetlbfs_fs() forgot to use it.
