USB: add Zoom Telephonics Model 3095F V.92 USB Mini External modem to cdc-acm

The patch below is a necessary workaround to support the Zoom Telephonics Model 3095F V.92 USB Mini External modem, which fails to initialise properly during normal probing thus:

May  3 22:53:00 imcfarla kernel: drivers/usb/class/cdc-acm.c: Zero length descriptor references
May  3 22:53:00 imcfarla kernel: cdc_acm: probe of 5-2:1.0 failed with error -22

Adding the patch below causes the probing section to be skipped, and the modem
then initialises correctly.
