[PATCH v4 0/2] xfs: Fix compiler warnings

[Allison Collins]

Some variables added in the delayed attr series were only used in ASSERT
checks, and caused some compiler warnings.  This set fixes these warnings by
removing the convenience variable.

  xfs: Fix compiler warning in xfs_attr_node_removename_setup
  xfs: Fix compiler warning in xfs_attr_shortform_add
