crypto: scompress - initialize per-CPU variables on each CPU
In commit 71052dcf4be70 ("crypto: scompress - Use per-CPU struct instead multiple variables") I accidentally initialized multiple times the memory on a random CPU. I should have initialize the memory on every CPU like it has been done earlier. I didn't notice this because the scheduler didn't move the task to another CPU. Guenter managed to do that and the code crashed as expected. Allocate / free per-CPU memory on each CPU.
