cluster/tier : Fix double free in tier process

The tier process tries to free ipc_ctr_params twice
if the syncop_ipc call in tier_process_ctr_query fails.
ipc_ctr_params is freed when ctr_ipc_in_dict is freed.
But ctr_ipc_out_dict is NULL when syncop_ipc fails, causing
GF_FREE to be called on a non-NULL ipc_ctr_params ptr again.
