lib/idr.c: fix rcu related race with idr_find ...
2nd part of the fixes needed for
http://bugzilla.kernel.org/show_bug.cgi?id=11796 .
When the idr tree is either grown or shrunk, then the update to the number
of layers and the top pointer were not atomic. This race caused crashes.
The attached patch fixes that by replicating the layers counter in each
layer, thus idr_find doesn't need idp->layers anymore.
