mlxsw selftests often invoke a bail_on_lldpad() helper to make sure LLDPAD is not running, to prevent conflicts between the QoS configuration applied through TC or DCB command line tool, and the DCB configuration that LLDPAD might apply. This helper might be useful to others. Move the function to lib.sh, and parameterize to make reusable in other contexts.
