Low-Mem devices: zram-swap does not work anymore

[Noki]

Low memory devices should load zram-swap:

bbb-configs/roles/cfg_openwrt/tasks/conditional_packages.yml

Lines 36 to 41 in 5069887

	- name: "Add zram-swap on low mem and big flash"
	set_fact:
	packages: "{{ packages + ['zram-swap'] }}"
	when:
	- low_mem | default(false)
	- not (low_flash | default(false))

This however results in the following error:

Thu Oct 24 00:51:16 2024 daemon.crit zram_start: kernel doesn't support swap
Thu Oct 24 00:51:16 2024 daemon.notice procd: /etc/rc.d/S15zram: zram_start: kernel doesn't support swap

We should either stop loading zram-swap or make the kernel support it.
