[dts] [PATCH V2] tests/pvp_multi_paths_virtio_single_core_performance:remove vectorized=0 by default in test case 9 and optimize code

[Ling Wei <weix.ling@intel.com>]

Remove vectorized=0 by default in test case 9 and 
use pmd.start_testpmd() to replace session.send_expect() 
to start and quit testpmd.

v1:
Remove vectorized=0 by default in test case 9 and
use pmd.start_testpmd() to replace session.send_expect()
to start and quit testpmd.

v2:
Fix close_all_session self.vhost to self.virtio_user0.
