    vm: trigger garbage collection on kernel memory pressure
    
    In addition to physical pages, the slab allocator also consumes kernel
    virtual memory, so reclaim pages on failure to allocate from a kernel map.
    This method isn't foolproof but helps alleviate fragmentation.
    
    * vm/vm_kern.c (kmem_alloc): Call slab_collect and retry allocation
    once on failure.
    (kmem_realloc): Likewise.
    (kmem_alloc_wired): Likewise.
    (kmem_alloc_wired): Likewise.
    (kmem_alloc_aligned): Likewise.
