This commit shows oops in zram_inc_stat() which does not exist in
staging tree version of zram. Its actually a problem with zram version
as present in project's own repository where we allocate struct
zram_stats_cpu upon device initialization. OTOH, In mainline/staging
version of zram, we allocate struct stats upfront, so this oops cannot
happen in mainline version.
So, this commit is not even applicable for mainline/staging tree. My
bad, I didn't get a chance to review that patch.

I will now end development on local project repository and sync it with
the mainline version, so all future development happens on
mainline/staging only, avoiding such confusions in future.
