devnode: improve the demuxer function
Handle multiple request types as recommended by the Mach Server
Writer's Guide section 4, subsection "Handling Multiple Request
Types". This avoids initializing the reply message in every X_server
function. The reply message has already been properly initialized in
libports, so there is no need to call mig_reply_setup.
* devnode/devnode.c (devnode_demuxer): Improve the demuxer function.
