[NETFILTER]: Fix OOPSes on machines with discontiguous cpu numbering.

Browse source 
Original patch by Harald Welte, with feedback from Herbert Xu
and testing by S�bastien Bernard.

EBTABLES, ARP tables, and IP/IP6 tables all assume that cpus
are numbered linearly.  That is not necessarily true.

This patch fixes that up by calculating the largest possible
cpu number, and allocating enough per-cpu structure space given
that.
