modules: fix incorrect percpu usage
Mainline does not need this fix, as commit
259354deaaf03d49a02dbb9975d6ec2a54675672 fixed the problem by refactoring.
Should use per_cpu_ptr() to obfuscate the per cpu pointers (RELOC_HIDE is needed
for per cpu pointers).
Introduced by commit:
module.c: commit 6b588c18f8dacfa6d7957c33c5ff832096e752d3
This patch should be queued for the stable branch, for kernels 2.6.29.x to
2.6.33.x. (tested on 2.6.33.1 x86_64)
