With the on-media inventory now being restored for multiple streams we
can see that the restored streams both claim to be for /dev/nst0.

[root@rhel8 xfsdump-dev]# xfsdump -L "Test" -f /dev/nst0 -M tape1 -f /dev/nst1 -M tape2 /boot
...
[root@rhel8 ~]# rm -rf /var/lib/xfsdump/inventory
[root@rhel8 xfsdump-dev]# restore/xfsrestore -L Test -f /dev/nst0 -f /dev/nst1 /tmp/test

Fix this by indexing the stream being packed for the on-media inventory.
