Summary

Some auditing of the code shows that "cred" is never non-NULL in these
functions, either because all callers pass a non-NULL reference or
because they unconditionally dereference "cred". So, let's simplify the
code a bit and remove NULL checks. No functional change intended.

May be add documenting MPASS(cred) here and in other functions?

If you really prefer it I will do it, but to me it's overkill. These functions are not providing general-purpose interfaces, so it's ok to make assumptions like this IMO.

Just suggested! If you disagree, let it be your way :)
