[Bugfix]Fix userspace-reboot failure when backing_dev exists but zram not swapped on
'/sys/block/zram0/backing_dev' will exist even if zram is not swapped on in some devices. And there is no reason to ensure that zram is swapped on if '/sys/block/zram0/backing_dev' exists. So, if we want to kill backing_dev during userspace reboot, we should check if zram is swapped on first.
TEST: as follow
- adb root
- adb shell swapoff /dev/block/zram0
- adb shell echo 1 > /sys/block/zram0/reset
- adb shell setprop test.userspace.reboot.flag 1
- adb reboot userspace
- (wait reboot ending) adb shell getprop test.userspace.reboot.flag (1 will be show if successful)
