[PATCH v9 13/24] xfs: Remove unneeded xfs_trans_roll_inode calls

[Allison Collins <allison.henderson@xxxxxxxxxx>]

Some calls to xfs_trans_roll_inode and xfs_defer_finish routines are not
needed. If they are the last operations executed in these functions, and
no further changes are made, then higher level routines will roll or
commit the tranactions. The xfs_trans_roll in _removename is also not
needed because invalidating blocks is an incore-only change.
