Title: Fix null pointer dereference when server goes away

Fixes a panic when a node goes away.

How to reproduce:
- Start Riak
- Connect with mrb/riakpbc
- Stop Riak

Expected result:
- Nothing happens immediately, an error is returned on future requests if nodes are down

Actual result:
- Immediately panics on null pointer dereference
