[PULL 1/5] hw/nvme: move adjustment of data_units{read,written}

[Klaus Jensen <its@irrelevant.dk>]

From: Joel Granados <j.granados@samsung.com>

Move the rounding of bytes read/written into nvme_smart_log which
reports in units of 512 bytes, rounded up in thousands. This is in
preparation for adding the Endurance Group Information log page which
reports in units of billions, rounded up.
