[dts] [PATCH V1] tests/ice_dcf_flow_priority: fix script

[Jiale Song <songx.jiale@intel.com>]

there is a logic issue in the script. when the app starts for a timeout, the app that may 
start successfully will not be closed in teardown, affecting the testing of other cases. 
fix it and delete some useless code.
