USB: gadget: Add ID numbers to gadget names
Putting USB gadgets on a new bus of their own encounters a problem
when multiple gadgets are present: They all have the same name! The
driver core fails with a "sys: cannot create duplicate filename" error
when creating any of the /sys/bus/gadget/devices/<gadget-name>
symbolic links after the first.
This patch fixes the problem by adding a ".N" suffix to each gadget's
name when the gadget is registered (where N is a unique ID number),
thus making the names distinct.
