[PATCH] lightnvm: pblk: assume that chunks are closed on 1.2 devices

[Hans Holmberg]

From: Hans Holmberg <hans.holmberg@xxxxxxxxxxxx>

We can't know if a block is closed or not on 1.2 devices, so assume
closed state to make sure that blocks are erased before writing.

Fixes: 32ef9412c114 ("lightnvm: pblk: implement get log report chunk")
