nvme-rdma: fix in-casule data send for chained sgls
We have only 2 inline sg entries and we allow 4 sg entries for the send
wr sge. Larger sgls entries will be chained. However when we build
in-capsule send wr sge, we iterate without taking into account that the
sgl may be chained and still fit in-capsule (which can happen if the sgl
is bigger than 2, but lower-equal to 4).
Fix in-capsule data mapping to correctly iterate chained sgls.
