scsi: libsas: Remove an empty branch in sas_check_parent_topology()

Browse source

There is an empty "all good" branch in sas_check_parent_topology(). We can
reverse the test statement and remove the empty branch.

Moreover, factor out a helper sas_check_edge_expander_topo() to make the
code more readable.
