libnvdimm: fix badblock range handling of ARS range
commit 4e3f0701f25ab194c5362576b1146a1e6cc6c2e7 upstream.
__add_badblock_range() does not account sector alignment when
it sets 'num_sectors'. Therefore, an ARS error record range
spanning across two sectors is set to a single sector length,
which leaves the 2nd sector unprotected.
Change __add_badblock_range() to set 'num_sectors' properly.
