Pull UBIFS fixes from Artem Bityutskiy:
 "Two patches which fix a problem reported by several people in the
  past, but only fixed now because no one gave enough material for
  debugging.

  Anyway, these fix the problem that sometimes after a power cut the
  file-system is not mountable with the following symptom:

	grab_empty_leb: could not find an empty LEB

  The fixes make the file-system mountable again."
