BLK_STS_NEXUS is used for nvme/scsi reservation conflicts and also
general nexus failures. For the pr_ops use we want to know if an IO failed
for specifically a reservation conflict so we can report that error upwards
to a VM. This patch adds a new error code for this case and converts nvme.
The next patch converts scsi because it's a little more complicated.

Please fix the spelling of "reservation".
