rapidio: use device lists handling on per-net basis

Browse source 
Modify handling of device lists to resolve issues caused by using single
global list of RIO devices during enumeration/discovery.  The most common
sign of existing issue is incorrect contents of switch routing tables in
systems with multiple mport controllers while single-port configuration
performs as expected.
