mm/slab: Add kvfree_atomic() helper
kvmalloc() now supports non-sleeping GFP flags, including
the vmalloc fallback path. This means it may return vmalloc
memory even for GFP_ATOMIC and GFP_NOWAIT allocations.
Freeing such memory with kvfree() may then end up calling
vfree(), which is not safe for non-sleeping contexts.
Introduce kvfree_atomic() helper for such cases. It mirrors
kvfree(), but uses vfree_atomic() for vmalloced memory.
