TTY: pty, remove superfluous ptm test
The code looks like:
if (tty->driver->subtype == PTY_TYPE_MASTER) {
...
if (tty->driver == ptm_driver)
But the second if is superfluous because only the ptm_driver is of
PTY_TYPE_MASTER subtype.
Also we can remove the #if now because devpts_pty_kill is defined as
an empty function for non-CONFIG_UNIX98_PTYS configs.
