libcgrouptest: Initialize uninitialized pointers in test cases
libcgrouptest: Initialize uninitialized pointers in test cases

Pointers should be initialized to NULL. In the multi mount test case
path, we had an uninitialized cgroup_filled which caused a
segmentation fault. Fix it for this test case.

TODO:
Fix for all test cases.
