[SPARC64]: Fix build failure when CONFIG_BUG is disabled.

When CONFIG_BUG is turned off, the standard trick of:

switch (x) {
case X:
...
case Y:
...
default:
BUG();
};

to mark impossible cases does not work because BUG() evalutes
to nothing and thus GCC just sees a fallthrough code path.

Add an explicit KERN_ERR log message and a do_exit() to trap
this case.
