xfs: vectorise directory data operations

Browse source 
Following from the initial patches to vectorise the shortform
directory encode/decode operations, convert half the data block
operations to use the vector. The rest will be done in a second
patch.

This further reduces the size of the built binary:

   text    data     bss     dec     hex filename

 792350   96802    1096  890248   d9588 fs/xfs/xfs.o.p2
