[PATCH 04/67] xfs: move ->iop_recover to xfs_defer_op_type

["Darrick J. Wong" <djwong@xxxxxxxxxx>]

From: Darrick J. Wong <djwong@xxxxxxxxxx>

Source kernel commit: db7ccc0bac2add5a41b66578e376b49328fc99d0

Finish off the series by moving the intent item recovery function
pointer to the xfs_defer_op_type struct, since this is really a deferred
work function now.
