USB: serial: fix initial-termios handling

A few drivers override the default initial termios settings provided by USB serial core, but due to a long-standing bug, the terminal settings were being reset on every (first) open rather than on first use after probe as intended.

This series fixes the bug and cleans up the various init_termios implementations somewhat.
