USB: cdc-acm: only raise DTR on transitions from B0 commit 4473d054ceb572557954f9536731d39b20937b0c upstream. Make sure to only raise DTR on transitions from B0 in set_termios. Also allow set_termios to be called from open with a termios_old of NULL. Note that DTR will not be raised prematurely in this case.
