Darrick J. Wong b5325a02aa ttyprintk: Fix NULL pointer deref by setting tty_port ops after initializing port ...

tty_port_init() zeroes out the tty port, which means that we have to set the
ops pointer /after/, not before this call.  Otherwise, tty_port_open will crash
when it tries to deref ops, which is now a NULL pointer.
