Fix cluster.c inet_ntop use of sizeof(n->ip).

Browse Source 
Using sizeof with an array will only return expected results if the
array is created in the scope of the function where sizeof is used. This
commit changes the inet_ntop calls so that they use the fixed buffer
value as defined in redis.h which is 16.
