**- Why I did it**
The tx_disable function isn't work for the accton_ax5835-54x device.
**- How I did it**
Fix the incorrect path of the sfp node path inside the util file.
**- How to verify it**
Test with
"sudo accton_as5835_54x_util.py show"
"sudo accton_as5835_54x_util.py set sfp"
There should see correct value for module_present and module_tx_disable. And should able to set it.
