Leak less memory.

Now, is there any reason that the prs_init() doesn't use the talloc context
that it is supplied as an argument for the actual data buffer?

It would seem logical to replace the malloc with a talloc, but I'm sure
there is some method to the madness (extrnal use/Reallocing of it I presume)
