[PATCH v7 02/19] xfs: Embed struct xfs_name in xfs_da_args

[Allison Collins <allison.henderson@oracle.com>]

This patch embeds an xfs_name in xfs_da_args, replacing the name, namelen, and flags
members.  This helps to clean up the xfs_da_args structure and make it more uniform
with the new xfs_name parameter being passed around.
