    devlink: bump the instance index directly when iterating
    
    xa_find_after() is designed to handle multi-index entries correctly.
    If a xarray has two entries one which spans indexes 0-3 and one at
    index 4 xa_find_after(0) will return the entry at index 4.
    
    Having to juggle the two callbacks, however, is unnecessary in case
    of the devlink xarray, as there is 1:1 relationship with indexes.
    
    Always use xa_find() and increment the index manually.
