virtio-serial-bus: use correct lengths in control_out() message
Original code has one thing to process (cur_len), requests to convert from iovec to buf another thing (len which is actually max_len), and processes something else (copied). Whole thing is very difficult to understand, even if it does a right thing. The iov_to_buf() conversion in this case will always return cur_len, because it is the length of the iovec it was asked to process, and the size we asked to convert is the same or larger, and iov_to_buf() will stop at reaching either iov or buf. Make the code saner by doing the only sane thing: dropping `copied' which is always the same as `cur_len' but just introduces questions. Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>
