[PATCH] use core driver name for ATM device

[Roman Kagan]

  Hi Duncan,

This one-liner fixes the case when subdriver's module gets unloaded,
thus its .driver_name gets destroyed, while ATM still holds a reference
to it.  It passes instead usbatm_driver_name to ATM.

Alternatively we can make a private copy of subdriver's .driver_name and
release it in usbatm_destroy_instance, but it doesn't seem to be worth
to bother.

Cheers,
  Roman.
