net: ocelot: Add of_node_put() before return statement
Every iteration of for_each_available_child_of_node() decrements
the reference count of the previous node, however when control
is transferred from the middle of the loop, as in the case of
a return or break or goto, there is no decrement thus ultimately
resulting in a memory leak.
Fix a potential memory leak in felix.c by inserting of_node_put()
before the return statement.
Issue found with Coccinelle.
