glusterd: dead code coverity fix

function: glusterd_volume_rebalance_use_rsp_dict

problem: Execution cannot reach this statement: "goto out;"

fix: removed the condition 'if(!ctx_dict)' and the corresponding action 'goto out;' because it will never be executed.
     reason: if the execution reaches this condition, then the value of '!ctx_dict' will always be false otherwise the execution will reach the 'out'
	     label, skipping the execution of this conditional statement.
