Kernels >4.7 will create a comp stream for each online CPU
and ignore /sys/block/max_compression_streams. This has been
backported to many 4.4 kernels as well.
Any device running a kernel with the upstream commit can safely remove
the parameter.
Upstream commit: 43209ea2d1

[libfs_mgr]Warning: unknown flag: zram_loopback_path=/data/per_boot/zram_swap
[libfs_mgr]Warning: unknown flag: zram_loopback_size=512M
We don't use zram_loopback_path any longer so remove it.
We also changed zram_loopback_size with zram_backingdev_size so correct it.
Bug: 145330273
Bug: 145116439
Test: confirmed there is no warning and zram backing device was configured

-Switch to LZ4 for better overall performance
-Set max_comp_streams to num of cores since upstream also moves this to
percpu.
-Set page-cluster to 0 as the incremental cost of reading 1 page at a
time is negligible for zram
Bug: 38249616
Test: boot and run zram-perf showing better performance
