/proc/net/atm initialization

From: Berkley Shands (berkley@cs.wustl.edu)

        When ATM is enabled, and any driver is loaded with the kernel
(not as a module), the init of atm_proc_root has not been done
when the driver inits. this leaves the driver putting its /proc data
into /proc, not in /proc/net/atm.
        This bug has existed for quite some time, and the patch has been
out on the linux-atm list for a while. Since there is no ATM or /proc entry
in MAINTAINERS, the SubmittingPatches file says send it here. OK,
here it is :-)
