xfs: avoid nested calls to __xfs_trans_commit
commit e96c1e2f262e0993859e266e751977bfad3ca98a upstream
Currently, __xfs_trans_commit calls xfs_defer_finish_noroll, which calls
__xfs_trans_commit again on the same transaction. In other words,
there's function recursion that has caused minor amounts of confusion in
the past. There's no reason to keep this around, since there's only one
place where we actually want the xfs_defer_finish_noroll, and that is in
the top level xfs_trans_commit call.
