Calling fetch_attributes() without parameters does not work as expected here:
The first step (CMD_RSM_ATTR_GETALL) works as expected and returns a very long list of parameters.
The second step with a call to CMD_RSM_ATTR_GET with a very long argument fails.
In /var/log/zebra-scanner/corescannerd/CLIENTLIB_COMMON_2020.10.07_13-27-47_001.log the error is:

I have a Zebra MS4717 fixed mount scanner.

With this patch I can call fetch_attributes() for the parameters I actually care about.
