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.
