slub: Use alloc_pages_exact_node() for page allocation
The alloc_slab_page() in SLUB uses alloc_pages() if node is '-1'. This means that node validity check in alloc_pages_node is unnecessary and we can use alloc_pages_exact_node() to avoid comparison and branch as commit 6484eb3e2a81807722 ("page allocator: do not check NUMA node ID when the caller knows the node is valid") did for the page allocator.
