virtio-serial: Handle scatter-gather buffers for control messages
Current control messages are small enough to not be split into multiple
buffers but we could run into such a situation in the future or a
malicious guest could cause such a situation.
So handle the entire iov request for control messages.
Also ensure the size of the control request is >= what we expect
otherwise we risk accessing memory that we don't own.
