tty: fix unused warning when TCGETX is not defined
If TCGETX is not defined, we end up with this warning: drivers/char/tty_ioctl.c: In function ‘tty_mode_ioctl’: drivers/char/tty_ioctl.c:950: warning: unused variable ‘ktermx’ Since the variable is only used in one case statement, push it down to the local case scope.
