nvme: lightnvm: return ppa completion status
PPAs sent to device is separately acknowledge in a 64bit status
variable. The status is stored in DW0 and DW1 of the completion queue
entry. Store this status inside the nvm_rq for further processing.
This can later be used to implement retry techniques for failed writes
and reads.
