Revert "Enable zram writeback"
This reverts commit 2e40dfa104b14e52288285648f71869fea97df29.
This CL will make zRAM job scheduler and zram-writeback standalone
mode(e.g., adb) void.
Bug: 140879284
Test: On coral device, "dumpsys jobscheduler" | grep Zram is NULL
Test: check followings on sargo device
1. cat /sys/block/zram0/backing_dev is NULL
2. echo all > /sys/block/zram0/idle;
echo idle > /sys/block/zram0/writeback;
cat /sys/block/zram0/bd_stat is NULL
