volser: Don't initialise all error tables

Initialising the KA and cmd error tables in vsprocs.c makes the
libvolser library dependent upon rxkad and cmd. As we may want to
use that library in programs which use neither rxkad, nor our command
processor, this is less than ideal. So, just drop the initialisations.
