r23783: Processing the UAS change message was causing problems on ppc64 Linux

systems. Rather than trying to fix this, it's much better just to
remove the code, as it serves no purpose at all (the message that is
generated is ignored by smbd).

This sort of parsing should really be done by PIDL generated code.
(This used to be commit 22e8404cef4961f7468a9f24e23024c827233b84)
