Add Exception handling when processing udev devices (#5088)

* Add Exception handling to UDEV reading and parsing

Khadas VIM4 UDEV returns something that python crapps its pants about. The exception just allows it to continue.

* Add an exception print

Added an exception print for the times things go bad.

* Split exception handling

The exception is not fatal when parsing error happens on one node. print it and continue.

* cleanups

* swapped functions

device.device_node   function bails very badly!  It raises no exceptions to the top but complains and errors

* Update supervisor/hardware/manager.py
