The return type of atomic64_read() is unfortunately architecture
specific, it can be 'long', 'long long', or 's64'. When it is 'long',
we get a build warning:

Add an explicit cast to 's64' to get a consistent behavior on all
architectures here during compile testing.

This patch doesn't apply to cryptodev because the bug has already
been fixed by another patch.
