Subject: [PATCH] crypto: caam: fix type mismatch warning

Building the caam driver on arm64 produces a harmless warning:

drivers/crypto/caam/caamalg.c:140:139: warning: comparison of distinct pointer types lacks a cast

We can use min_t to tell the compiler which type we want it to use
here.

Fixes: 5ecf8ef9103c ("crypto: caam - fix sg dump")

This is currently the only warning reported by kernelci.org for
linux-4.9 on arm, arm64 and x86.
