Seems to work for me now.

[root@bp-01 ~]# lvs vg
  LV   VG   Attr       LSize  Pool        Origin     Data%  Meta%  Move Log Cpy%Sync Convert
  lv   vg   Cwi-a-C--- 50.00g [cachepool] [lv_corig] 0.04   2.83            0.00

[root@bp-01 ~]# lvchange -p rw vg/lv
  Logical volume "lv" is already writable
[root@bp-01 ~]# lvchange -p r vg/lv
  Logical volume "lv" changed.
[root@bp-01 ~]# lvchange -p rw vg/lv
  Logical volume "lv" changed.
[root@bp-01 ~]# lvchange -p r vg/lv
  Logical volume "lv" changed.

[root@bp-01 ~]# vgremove vg
Do you really want to remove volume group "vg" containing 1 logical volumes? [y/n]: y
Do you really want to remove active logical volume lv? [y/n]: y
  Logical volume "cachepool" successfully removed
  Logical volume "lv" successfully removed
  Volume group "vg" successfully removed

The version I tested was lvm2-2.02.115-3.el7.x86_64 - just one bump beyond what you tested.
