coverity: fix possible NULL dereference

Browse Source 
The call to dm_config_destroy can derefence result->mem
while result is still NULL:

struct dm_config_tree *get_cachepolicy_params(struct cmd_context *cmd)
{
	...
	int ok = 0;
	...
	if (!(result = dm_config_flatten(current)))
		goto_out;
	...
	ok = 1;
out:
	 if (!ok) {
		dm_config_destroy(result)
		...
	}
	...
}
