xfs_repair: set rsumino version to 2
If we run xfs/033 with "-m crc=0", the test fails with a repair
output difference:
Phase 7 - verify and correct link counts...
+resetting inode INO nlinks from 0 to 1
done
This is because when we zero out the realtime summary inode and
rebuild it, we set its version to 1, then set its ip->i_d.di_nlink
to 1. This is a little odd, because v1 inodes store their link
count in di_onlink...
Then, later in repair we call xfs_inode_from_disk(), which sees the
version one inode, and converts it to version 2 in part by copying
di_onlink to di_nlink. But we never *set* di_onlink, so di_nlink
gets reset to zero, and this error is discovered later in repair.
Interestingly, mk_rbmino() was changed in 138659f1 to set version 2;
it looks like mk_rsumino was just missed.
