Fix use of lookup_next_index in LISP src/dst FIB
Adjacencies in LISP src/dst FIB store the index of the LISP output interface (next node after lookup) in the lookup_next_index. Since the values of interface node indexes are not constrained, they can collide with the 'special' adjacencies IP_LOOKUP_NEXT_LOCAL and IP_LOOKUP_NEXT_DROP. As a result, at allocation time, LISP ajacencies may be automatically shared with the previous two, predefined adjacencies and all LISP specific state stored in the rewrite area is lost. This fixes the problem by 'hijacking' the explicit_fib_index instead of the lookup_next_index field.
