Update SMPng task list

Browse source 
- Alfred has pushed down Giant for a number of fd-related operations,
  including read/write/pread/pwrite, +other consumers into the per-subsystem
  fileop code.  Record this as done.

- Add a task to push down Giant for the remaining such calls, including
  readv/writev which currently still require Giant for memory management
  in handling struct iovec arrays.  Record this as un-owned.
