isci: make a remote_node_context a proper member of a remote_device
A rnc object has the same lifetime as its associated remote_device. It might get re-initialized, but a remote device always has an rnc member. Preparation for unifying scic_sds_remote_device and isci_remote_device Signed-off-by: Dan Williams <dan.j.williams@intel.com>
