We want to switch from qemu_socket_set_block() to newer qemu_set_blocking(), which provides return status of operation, to handle errors. Still, we want to keep qio_channel_socket_readv() interface clean, as currently it allocate @fds only on success. So, in case of error, we should close all incoming fds and keep user's @fds untouched or zero. Let's make separate functions qio_channel_handle_fds() and qio_channel_cleanup_fds(), to achieve what we want. Reviewed-by: Daniel P.
