[PATCH v2] nvme: return BLK_STS_OK on success in nvme_setup_rw

[Vincent Fu]

Return BLK_STS_OK instead of 0 on success. Since BLK_STS_OK is defined
as 0 this patch results in no functional change but to avoid confusion
and to be consistent with nvme_setup_write_zeroes as well as
nvme_setup_discard we should have nvme_setup_rw also return BLK_STS_OK.
