And besides this, in nvme_fc_complete_rq() it is called before
nvme_fc_unmap_data() in nvme_fc_start_fcp_op() afterwards. Even if this is a
correct behaviour (i.e. doesn't harm as we're not touching
req->special_vec.bv_page in nvme_fc_unmap_data() it at a first sight looks
like an error. Care to adjust it?

Byte,
