RDMA/core: Introduce "name_assign_type" for an IB device
The name_assign_type indicates how the name is provided. Currently
these types are supported:
- RDMA_NAME_ASSIGN_TYPE_UNKNOWN: Unknown or not set;
- RDMA_NAME_ASSIGN_TYPE_USER: Name is provided by the user; The
user-created sub device, rxe and siw device has this type.
When filling nl device info, it is set in the new attribute
RDMA_NLDEV_ATTR_NAME_ASSIGN_TYPE. User-space tools like udev
"rdma_rename" could check this attribute to determine if this
device needs to be renamed or not.
