usb_serial: Fix oops when unexisting usb serial device is opened.
This commit 335f8514f200e63d689113d29cb7253a5c282967 has stopped
properly checking if there is any usb serial associated with the tty in
the close function. It happens the close function is called by releasing
the terminal right after opening the device fails.
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.
