[patch][wip] staging: unisys: kmalloc/memset move to kzalloc

[Silvio F]

Hi,

I have followed this thread and have seen that not all parts was kcalloc'ized.
Please review this patch and maybe include it.

This patch is WIP because I have  no hardware and can only do a compile test.

version 2:
* remove ALLOC_CMDRSP define


Bye,
Silvio
