crypto: hisilicon - use kcalloc() instead of kzalloc()

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

Use devm_kcalloc() to gain built-in overflow protection, making memory
allocation safer when calculating allocation size compared to explicit
multiplication.
