init_reap_node() initialization fix

Browse Source 
It looks like there is a bug in init_reap_node() in slab.c that can cause
multiple oops's on certain ES7000 configurations.  The variable reap_node
is defined per cpu, but only initialized on a single CPU.  This causes an
oops in next_reap_node() when __get_cpu_var(reap_node) returns the wrong
value.  Fix is below.
