[dts] [PATCH V2] tests/malicious_driver_event_indication:code for optimizing the start mode of VF

[Zhou Jun <junx.w.zhou@intel.com>]

v1:
the original way:copy testpmd to another file and start VF
now:start VF with another profix file on the testpmd start PF 

v2:
modifying nonstandard variable naming
