audiopolicy: fix routing of exclusive preferred device 



In call music played on remote is called an "exclusive" preferred
device. It may not be propagated to other client that may play locally.
The client of the exclusive preferred device is not routed as the
exclusive preferred device are ignored from findPreferredDevice helper.

This CL fixes the routing
