libdiskfs: improve the diskfs_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.
Furthermore, move diskfs_exec_startup_server_routine to the end of the
chain, as the startup related functions are only needed at system
bootstrap time in the root filesystem.
* libdiskfs/demuxer.c (diskfs_demuxer): Improve the demuxer function.
