4.5-stable review patch. If anyone has any objections, please let me know.

From: Wenwei Tao <ww.tao0320@xxxxxxxxx>
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.
