While I do appreciate your clean-up work, I would encourage you to ask
such questions on IRC or the mailing list, rather than just guessing and

In this case, the reason there is no mem_ctx parameter is that no memory
is returned, and so there is no reason that the caller should supply a
memory context.  

While there are other functions in Samba that take a memory context and
do not return memory, that should not be taken as precedent - in fact,
these should be tidied up so that they do not return memory.  As the
behaviour changes can be subtle, I ask that you allow me to review such
patches for you.
