Julia Lawall b34c7dcaf3 scsi: fnic: Use vmalloc_array() and vcalloc() 
Use vmalloc_array() and vcalloc() to protect against multiplication
overflows.

The changes were done using the following Coccinelle semantic patch:

// <smpl>
@initialize:ocaml@
@@

let rename alloc =
  match alloc with
    "vmalloc" -> "vmalloc_array"
  | "vzalloc" -> "vcalloc"
  | _ -> failwith "unknown"

    type t = {u8,__u8,char,unsigned char};
    identifier alloc = {vmalloc,vzalloc};
    fresh identifier realloc = script:ocaml(alloc) { rename alloc };
