mm/slub: remove slab_alloc() and __kmem_cache_alloc_lru() wrappers

Browse source

slab_alloc() is a thin wrapper around slab_alloc_node() with only one
caller.  Replace with direct call of slab_alloc_node().
__kmem_cache_alloc_lru() itself is a thin wrapper with two callers,
so replace it with direct calls of slab_alloc_node() and
trace_kmem_cache_alloc().

This also makes sure _RET_IP_ has always the expected value and not
depending on inlining decisions.
