gfs2: Large-filesystem fix for 32-bit systems
Commit ff34245d switched from iget5_locked to iget_locked among other things, but iget_locked doesn't work for filesystems larger than 2^32 blocks on 32-bit systems. Switch back to iget5_locked. Filesystems larger than 2^32 blocks are unrealistic to work well on 32-bit systems, so this is mostly a code cleanliness fix.
