Use a separate array allocation for the execbuf vma, so that we can track their lifetime independently from the copy of the user arguments. With luck, this has a secondary benefit of splitting the malloc size to within reason and avoid vmalloc. The downside is that we might require two separate vmallocs -- but much less likely. In the process, this prevents a memory leak on the ww_mutex error unwind.
