migration: use a single I/O operation when writev_buffer is not defined
The recent patches to use vectored I/O for RAM migration caused a
regression in savevm speed. To restore previous performance,
add data to the buffer in qemu_put_buffer_async whenever writev_buffer
is not available in the QEMUFile.
