From: Dave Chinner <dchinner@xxxxxxxxxx>

Convert the rest of the directory data block encode/decode
operations to vector format.

This further reduces the size of the built binary:

   text    data     bss     dec     hex filename

 792986   96802    1096  890884   d9804 fs/xfs/xfs.o.p1
 792350   96802    1096  890248   d9588 fs/xfs/xfs.o.p2
