cciss: add BUILD_BUG_ON() for catching bad CommandList_struct alignment

The hardware requires 64-bit alignment of commands, so add a build bug
check for that. The recent commit dfb0edd4d055d525bc1e8bd9d71d0ec67db18847
didn't change the size of the command, but other additions/changes may and
thus break badly at runtime.
