[libfix] Fix framework break due to geo_rep patch

Problem:
Due to patch [1], the framework broke and
was failing for all the testcases with the below
backtrace:
```
>  mount_dict['server'] = cls.snode
E AttributeError: type object 'VolumeAccessibilityTests_cplex_replicated_glusterf'
has no attribute 'snode'
```

Solution:
This was becasue mnode_slave was accidentally written as snode. And
cls.geo_rep_info wasn't a safe condition operator hence changed it
to cls.slaves.

Testcase results with patch:
