RDMA/core: Implement compat device/sysfs tree in net namespace
Implement compatibility layer sysfs entries of ib_core so that non init_net net namespaces can also discover rdma devices. Each non init_net net namespace has ib_core_device created in it. Such ib_core_device sysfs tree resembles rdma devices found in init_net namespace. This allows discovering rdma devices in multiple non init_net net namespaces via sysfs entries and helpful to rdma-core userspace.
