zram doesn't work on msm8953

Describe your issue

zram doesn't work: zramctl: /dev/zram0: failed to set algorithm: Invalid argument

probably because zstd is not enabled in the kernel

markw:~$ sudo service zram-init restart

Additional information

zram doesn't work with the default zstd compression algorithm. Although I can enable it if I set lz4 for example:

markw:~$ sudo zramctl /dev/zram0 --algorithm zstd --size 1000MiB
zramctl: /dev/zram0: failed to set algorithm: Invalid argument
markw:~$ sudo zramctl /dev/zram0 --algorithm lz4 --size 1000MiB
markw:~$
