tty: remove file from tty_mode_ioctl
The only user of 'file' parameter in tty_mode_ioctl is a BUG_ON check.
Provided it never crashed for anyone, it's an overkill to pass the
parameter to tty_mode_ioctl only for this check.
If we wanted to check 'file' there, we should handle it in more graceful
way anyway. Not by a BUG == crash.
