migration/rdma: Clean up two more harmless signed vs. unsigned issues

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.
