mod_pubsub: Fix get_max_items_node/1 specification 

Make it explicit that the get_max_items_node/1 function returns
?MAXITEMS if the 'max_items_node' option isn't specified.  The function
didn't actually fall back to 'undefined' (but to the 'max_items_node'
default; i.e., ?MAXITEMS) anyway.  This change just clarifies the
behavior and adjusts the function specification accordingly.
