ipack: ipoctal: fix tty registration race
commit 65c001df517a7bf9be8621b53d43c89f426ce8d6 upstream.
Make sure to set the tty class-device driver data before registering the
tty to avoid having a racing open() dereference a NULL pointer.
Fixes: 9c1d784afc6f ("Staging: ipack/devices/ipoctal: Get rid of ipoctal_list.")
