kernel: start cleaning up VfsRequest

* I'm being more strict about the linked list state to hopefully ensure
  I'm not leaking any references.
* vfsreq_create was renamed to vfsreq_dispatchcopy as that name feels more
  clear. It copies its argument, and dispatches it.
* Requests for user backends are now handled more like requests for kernel
  backends - there's an accept() function that accepts a request.
