As follows from #define NAME_TEMPLATE, the procfs code in the RNDIS driver
expects the # of instances to be 3-digit decimal, while the driver calls
ida_simple_get() passing 0 as the 'end' argument which results in actual
max instance # of INT_MAX.  Limit the maximum # of RNDIS instances to 1000
which is still a lot! :-)
