[PATCH] crypto: qat - use kcalloc() in qat_uclo_map_objs_from_mof()

[Qianfeng Rong]

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.
