cciss: Consolidate duplicate bits in cciss_cmd.h & cciss_ioctl.h 



There are several duplicate definitions in cciss_cmd.h and cciss_ioctl.h.
Consolidate these into the new cciss_defs.h file. This patch doesn't change
the definitions exposed under include/linux, so userspace apps shouldn't
be affected.
