[NET]: use __read_mostly on kmem_cache_t , DEFINE_SNMP_STAT pointers

Browse Source 
This patch puts mostly read only data in the right section
(read_mostly), to help sharing of these data between CPUS without
memory ping pongs.

On one of my production machine, tcp_statistics was sitting in a
heavily modified cache line, so *every* SNMP update had to force a
reload.
