api: crypto: reguire zero crypto range for null algs in OOP op type
Require that cipher range and auth range have zero offset and zero
length when used with null cipher and null auth algorithm, respectively,
with the out-of-place operation type.
This makes handling of ranges in the out-of-place operation type more
regular in that what gets copied to the output packet does not need to
treat null algorithms as a special case. This makes it also possible
to later allow non-null ranges with to-be-defined semantics with the OOP
op type in a backward compatible way.
