libnvdimm, btt: fix btt_rw_page not returning errors

btt_rw_page was not propagating errors frm btt_do_bvec, resulting in any
IO errors via the rw_page path going unnoticed. the pmem driver recently
fixed this in e10624f pmem: fail io-requests to known bad blocks
but same problem in BTT went neglected.
