Subject: null_blk: add lightnvm null_blk device to the nullb_list

From: Wenwei Tao <ww.tao0320@gmail.com>

commit 3681c85dffda70e551dead31c8d102bd69033fe8 upstream.

After register null_blk devices into lightnvm, we forget
to add these devices to the the nullb_list, makes them
invisible to the null_blk driver.
