isci: kill smp_discover_response_protocols in favor of domain_device.dev_type
This is step 1 of removing the contortions to: 1/ unparse expander phy data into a smp discover frame 2/ open-code-parse the smp discover fram into a domain_device.dev_type equivalent libsas has already spent cycles determining the dev_type, so now that scic_sds_remote_device is unified with isci_remote_device we can directly reference dev_type. This might also change multi-level expander detection as we previously only looked at dev_type == EDGE_DEV and we did not consider the FANOUT_DEV case.
