  MFC r323194:
  
  Fix remounting ZFS filesystem with "zfs mount"
  
  "zfs mount -o" passes a list of mount options directly to nmount(2) after
  sanity checking them. In particular, zfs(8) will refuse to mount an already
  existing file system unless "remount" is specified in the option list.
  However, the "remount" option only exists in Illumos. FreeBSD's equivalent is
  "update".
