[dts] [PATCH V1] tests/vf_offload: optimize script

[Song Jiale]

in general, vfs do not need to enable trust on. some intree drivers have
a issue that vfs with trust on cannot receive vf vlan packages, and
this issue will not be fixed. in order not to affect subsequent case
testing, do not enable trust on unnecessarily.
