Fix xfail for dir_bcast in dualtor (#6477)

What is the motivation for this PR?
xfail for dir_bcast in dualtor didn't work because 'dualtor' is not 'topo_type'

How did you do it?
Use 'topo_name' for dualtor instead of 'topo_type'
Fix order of conditional mark

How did you verify/test it?
Run test

Any platform specific information?
Supported testbed topology if it's a new test case?
