[PATCH 17/24] xfs: use ->t_dfops for collapse/insert range operations

[Brian Foster <bfoster@redhat.com>]

Use ->t_dfops for the collapse and insert range transactions. These
are the only callers of the respective bmap helpers, so replace the
unnecessary dfops parameters with direct accesses to ->t_dfops.
