[PATCH v11 11/25] xfs: Pull up xfs_attr_rmtval_invalidate

This patch pulls xfs_attr_rmtval_invalidate out of
xfs_attr_rmtval_remove and into the calling functions. Eventually
__xfs_attr_rmtval_remove will replace xfs_attr_rmtval_remove when we
introduce delayed attributes. These functions are exepcted to return
-EAGAIN when they need a new transaction. Because the invalidate does
not need a new transaction, we need to separate it from the rest of the
function that does. This will enable __xfs_attr_rmtval_remove to
smoothly replace xfs_attr_rmtval_remove later.
