On the inheritable-props branch: Remove some redundant code.
On the inheritable-props branch: Remove some redundant code.

* subversion/libsvn_client/iprops.c

  (need_to_cache_iprops): Delete, no callers.

  (svn_client__get_inheritable_props): Remove call to need_to_cache_iprops,
   while it was useful during development it's not needed any longer.  Why?
   Because since r1360860, when the NODES table began tracking WC roots via
   its inherited_props column, the results of
   svn_wc__get_cached_iprop_children will never give us a node that we
   don't need to cache iprops for.
