staging: dgnc: Fix a NULL pointer dereference

The error handling for print_drive after calling tty_alloc_driver()
was needed. But there was error handling but too late for this.
Error handling code moved after tty_alloc_driver() call.

Fixes: 60b3109e5e2d ("staging: dgnc: use tty_alloc_driver instead of kcalloc")
