Fix rehashing memory leaks

The pattern to move a key for various types (strings, sets, zsets,
hashes, etc) used a simple pattern:

1.  Construct the call in order to get all of the keys from the source
2.  Make a pass through call to the source node to get a response
3.  Use the response to make a pass through call to the destination node

The issue, however, was that we were using the same return value variable
for both source and destination nodes, so we would leak the response from
the source node.
