acm: Fix oops when closing ACM tty device right after open has failed.
This commit 10077d4a6674f535abdbe25cdecb1202af7948f1 has stopped
checking if there was a valid acm device associated to the tty, which is
not true right after open fails and tty subsystem tries to close the
device.
As an example, open fails with a non-existing device, when probe has
never been called, because the device has never been plugged. This is
common in systems with static modules and no udev.
