Hmmmm, I think the only place where we search through the list for a specific SSID is during remove_dev_pasid. We mostly use the list to iterate over all the masters/ssids that this domain is attached to. I'm not sure if moving to an xarray to optimize the remove_dev_pasid call is worth it (at the cost of iterations which IIUC would become N log(N))
