marker: do mq_reduce_parent_size_txn in FG for unlink & rmdir

* If a "rm -rf" is performed by a client, we initiate a
  marker background operation mq_reduce_parent_size_txn
  for rmdir and unlink.

  mq_reduce_parent_size_txn can fail when updating
  size on the ancestor directories, if these directories
  are removed during the txn as the child-parent association
  removed in the dentry list.

  So execute mq_reduce_parent_size_txn in foreground
  and then do the UNWIND for rmdir and unlink FOP
