While debugging Devloss and recovery, debugfs and sysfs
were found to not show the NVME port roles consistently.

The port role FC_PORT_ROLE_NVME_DISCOVERY was added with
the devloss bringup and the other issues were just oversight.

Add NVME Target and DISCSRVC to debugfs nodeinfo and sysfs
nvme info handlers. The full port role was added to the NVME
data only not the generic nodelist.
