Qianfeng Rong 2ced7045c9 crypto: qat - use kcalloc() in qat_uclo_map_objs_from_mof() 
[ Upstream commit 4c634b6b3c ]

As noted in the kernel documentation [1], open-coded multiplication in
allocator arguments is discouraged because it can lead to integer overflow.

Use kcalloc() to gain built-in overflow protection, making memory
allocation safer when calculating allocation size compared to explicit
multiplication.  Similarly, use size_add() instead of explicit addition
for 'uobj_chunk_num + sobj_chunk_num'.
