Nitin Gupta e983dc2428 Revert "Staging: zram: work around oops due to startup ordering snafu" 
This reverts commit 7e24cce38a because it
was never appropriate for mainline.

Do not check for init flag before starting I/O - zram module is unusable
without this fix.

The oops mentioned in the reverted commit message was actually a problem
only with the 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.

Checking for init_done flag in zram_make_request() results in a *no-op*
for any I/O operation since we simply always return success.  This flag
is actually set when the first write occurs on a zram disk which
triggers its initialization.
