USB: cdc_acm: Fix oops when Droids MuIn LCD is connected
commit fd5054c169d29747a44b4e1419ff47f57ae82dbc upstream.
The Droids MuIn LCD operates like a serial remote terminal.
Data received are displayed directly on the LCD. This patch
fixes the kernel null pointer oops when it is plugged in.
Add NO_DATA_INTERFACE quirk to tell the driver that "control"
and "data" interfaces are not separated for this device, which
prevents dereferencing a null pointer in the device probe code.
