      In case the lldp raw data collected by the inspection process includes non utf-8 information, the parser fails breaking the inspection process.
      This patch works around that excluding the malformed data and adding an entry in the logs to provide information on the failed tlv.

      We have a lab system that suddenly stopped being able to be deployed by the Assisted Installer; the BMH object is stuck in the "inspecting" state and has an event as follows:

      Unexpected exception UnicodeDecodeError during processing: 'utf-8' codec can't decode byte 0xf7 in position 13: invalid start byte

      Further investigation shows this is due to an error in processing an LLDP packet:
