lsmcli Test: Fix NO_STATE_CHANGE error in fs_child_dependancy_rm test.

Problem:
    The test will fail at NO_STATE_CHANGE error in fs_child_dependancy_rm
    test.

Root cause:
    Newly created file system does not have any child dependency.

Fix:
    Create a file system clone before calling fs_child_dependancy_rm().
