Tejun Heo ae9e6bc9f7 percpu: don't put the first chunk in reverse-map rbtree 
Impact: both first chunks don't use rbtree, no functional change

There can be two first chunks - reserved and dynamic with the former
one being optional.  Dynamic first chunk was linked on reverse-mapping
rbtree while the reserved one was mapped manually using the start
address and reserved offset limit.

This patch makes both first chunks to be looked up manually without
using the rbtree.  This is to help getting rid of the rbtree.
