Check isZramMaintenanceSupported on ZramMaintenance

Sending doZramMaintenanceAsync() request to mmd on the devices which
does not support zram writeback and zram recompression is useless.

Check the zram status before the first doZramMaintenanceAsync() and stop
the job scheduler loop of ZramMaintenance if the device does not support
zram maintenance.
