If /sys/block/zram0/mm_stat is missing then all /sys/block/zram*/mm_stat
files should be missing. But I don't want to terminate the test there
because the remaining 3 write tests could still find a regression. So
print a TCONF message on the first pass and silently skip the remaining
compression ratio checks.

I was also thinking about checking whether the write test filled the
test file at least up to 50% of memory limit if mm_stat doesn't exist.
But it'd mostly add unnecessary complexity.
