hugetlb: pass *next_nid_to_alloc directly to for_each_node_mask_to_alloc

With parallelization of hugetlb allocation across different threads, each
thread works on a differnet node to allocate pages from, instead of all
allocating from a common node h->next_nid_to_alloc.  To address this, it's
necessary to assign a separate next_nid_to_alloc for each thread.

Consequently, the hstate_next_node_to_alloc and
for_each_node_mask_to_alloc have been modified to directly accept a
*next_nid_to_alloc parameter, ensuring thread-specific allocation and
avoiding concurrent access issues.
