USB: serial/kobil_sct, fix potential tty NULL dereference

commit 6960f40a954619857e7095a6179eef896f297077 upstream.

Make sure that we check the return value of tty_port_tty_get.
Sometimes it may return NULL and we later dereference that.

The only place here is in kobil_read_int_callback, so fix it.
