xfs: remove struct xfs_attr_shortform
sparse complains about struct xfs_attr_shortform because it embeds a
structure with a variable sized array in a variable sized array.
Given that xfs_attr_shortform is not a very useful structure, and the
dir2 equivalent has been removed a long time ago, remove it as well.
Provide a xfs_attr_sf_firstentry helper that returns the first
xfs_attr_sf_entry behind a xfs_attr_sf_hdr to replace the structure
dereference.
