deb: Disable ZRAM

Browse source 
Meh. Even with the relatively good kernel impl this doesn't work
really good for us. New zram driver doesn't correlate very well
with our ancient code in mm. This leads to a noticeable performance
degradation when the kernel starts to swap the pages into zram disk and device
becomes a laggy mess after several days of uptime even without
very active usage.
