move compat handling of tty ioctls to tty_compat_ioctl()
ioctls that are
* callable only via tty_ioctl()
* not driver-specific
* not demand data structure conversions
* either always need passing arg as is or always demand compat_ptr()
get intercepted in tty_compat_ioctl() from the very beginning and
redirecter to tty_ioctl(). As the result, their entries in fs/compat_ioctl.c
(some of those had been missing, BTW) got removed, as well as
n_tty_compat_ioctl_helper() (now it's never called with any cmd it would accept).
