crypto: artpec6 - change from kzalloc to kcalloc in artpec6_crypto_probe()

Browse Source 
We are trying to get rid of all multiplications from allocation
functions to prevent potential integer overflows. Here the
multiplication is probably safe, but using kcalloc() is more
appropriate and improves readability. This patch has no effect
on runtime behavior.
