From: Markus Armbruster <arm...@redhat.com>
qemu_rdma_exchange_get_response() compares int parameter @expecting
with uint32_t head->type. Actual arguments are non-negative
enumeration constants, RDMAControlHeader uint32_t member type, or
qemu_rdma_exchange_recv() int parameter expecting. Actual arguments
for the latter are non-negative enumeration constants. Change both
parameters to uint32_t.
In qio_channel_rdma_readv(), loop control variable @i is ssize_t, and
counts from 0 up to @niov, which is size_t. Change @i to size_t.
While there, make qio_channel_rdma_readv() and
qio_channel_rdma_writev() more consistent: change the former's @done
to ssize_t, and delete the latter's useless initialization of @len.
