[ISDN]: Do not validate ISDN net device address prior to interface-up

   
Commit bada339b (Validate device addr prior to interface-up) caused a regression
in the ISDN network code, see: http://bugzilla.kernel.org/show_bug.cgi?id=9923
The trivial fix is to remove the pointer to eth_validate_addr() in the
net_device struct in isdn_net_init().
