[ALPS04682157] aee: ufs: Enable write permission for ufs_debug

Enable write permission for /proc/ufs_debug to try to catch
precise UFS command history in erroneous scenes by:

- Stopping UFS command history immediately just after error
  (e.g., NE, JE ...etc.) happens.
- Re-starting UFS command history after UFS command history
  is dumped.
