Currently the FC-NVMe driver is leverating the SCSI FC transport
class to access the remote ports. Which means that all FC-NVMe
remote ports will be visible to the fc transport layer, but due
to missing definitions the port roles will always be 'unknown'.
This patch adds the missing definitions to the fc transport class
to that the port roles are correctly displayed.
