Hi,

this is the V2 of the series to clean up the xfs_attr_sf_entry, addressing the
comments on the previous version.

Changelog details are in each patch description.

this series has been suggested by Eric, and it's intended as a small clean up
for xfs_attr_sf_entry usage.

In this series though, I reordered the typdef cleanups to be the first patches
in the series.
