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.
