This patch replaces the attribute name and length parameters with a
single struct xfs_name parameter.  This helps to clean up the numbers of
parameters being passed around and pre-simplifies the code some.

Indent the variable names, please.

Though I have this feeling that the huge series from hch that I just
reviewed will make this patch unnecessary...
