xfs: remove block number from inode lookup code
Upstream commit: 7b6259e7a83647948fa33a736cc832310c8d85aa
The block number comes from bulkstat based inode lookups to shortcut
the mapping calculations. We ar enot able to trust anything from
bulkstat, so drop the block number as well so that the correct
lookups and mappings are always done.
