[PATCH] lightnvm: introduce ADDR_PADDED to signal padding

[Javier GonzÃlez]

When REQ_FUA or REQ_FLUSH are sent from the block layer, a target might
need to pad some sectors in order to meet device constrains. ADDR_PADDED
allows to signal that such sector has been padded. It can be used to
mark both lbas and ppas.
