xfs: store an ops pointer in struct xfs_defer_pending
The dfp_type field in struct xfs_defer_pending is only used to either
look up the operations associated with the pending word or in trace
points. Replace it with a direct pointer to the operations vector,
and store a pretty name in the vector for tracing.
