Problem:
1, using contiguous conter for type identify is not uniform distribution
when compress for some tasks;
2, zram driver will alloc per-cpu contex for zstd, which will cause
about 3MB memory;
Solution:
1, using a fixed type array for uniform distribution of mix type
selection;
2, create 2 context: one dedicated for kswapd task; another one
dedicated for direct reclaim;

Problem:
kernel NULL pointer panic when cpu off line
Solution:
The root cause is that context for zram is configured as 2 part:
one for direct reclaim and one for kswapd. They are not for per-cpu
but when a core is off, zram will free per-cpu context so caused panic
on other cpus. So we should remove free code for crypto hooks.
