TTY/Serial driver fixes for 4.19-rc6

Here are a number of small tty and serial driver fixes for reported
issues for 4.19-rc6.

One should hopefully resolve a much-reported issue that syzbot has found
in the tty layer.  Although there are still more issues there, getting
this fixed is nice to see finally happen.

All of these have been in linux-next for a while with no reported
issues.
