6412 zfs receive: -u can be ignored sometimes

  It seems that zfs receive -F -u would mount a received filesystem after
  receiving a full stream if a destination filesystem already existed (and, thus,
  got destroyed and re-created) and was mounted.
  How to reproduce:
  $ zfs create rpool/sandbox
  $ zfs create rpool/sandbox/from
  $ zfs create rpool/sandbox/to
  $ zfs snap rpool/sandbox/from@snap
  $ zfs send rpool/sandbox/from@snap | zfs recv -v -F -u rpool/sandbox/to
  receiving full stream of rpool/sandbox/from@snap into rpool/sandbox/to@snap
  received 41.7KB stream in 1 seconds (41.7KB/sec)
  $ zfs get mounted rpool/sandbox/to
  NAME                  PROPERTY  VALUE    SOURCE
  rpool/tmp/sandbox/to  mounted   yes      -
  This behavior can be problematic if the mountpoint property changes either
  because it had a non-inherited value or the stream contains properties because
  it has been generated with either -R or -p.
