lightnvm: unconverted ppa returned in get_bb_tbl
The get_bb_tbl function takes ppa as a generic address, which is
converted to the ppa device address within the device driver. When
the update_bbtbl callback is called from get_bb_tbl, the device
specific ppa is used, instead of the generic ppa.
Make sure to pass the generic ppa.
