Linus Torvalds 23884007af tracing fixes for v7.1: 
- Avoid NULL return from hist_field_name()
 
   The function hist_field_name() is directly passed to a strcat()
   which does not handle "NULL" characters. Return a zero length
   string when size is greater than the limit.
 
   This is used only to output already created histograms and no
   field currently is greater than the limit. But it should still
   not return NULL.
 
 - Do not call map->ops->elt_free() on allocation failure
 
   When elt_alloc() fails, it should not call the map->ops->elt_free()
   function if it exists, as that function may not be able to handle
   the free on allocation failures. The ->elt_free() should only be
   called when elt_alloc() succeeds.
