        src/sys/arch/sh3/sh3: exception.c

Log Message:
For kernel mode address error, do not overwrite tf->tf_spc and tf->tf_r0
*before* checking pcb->pbc_onfault != NULL.

Should fix part of

PR port-sh3/56382
PR port-sh3/56401

i.e., DDB will no longer wrongly indicate NULL as fault PC for kernel mode
address error (and 0xe == EFAULT as r0).

Yes, we have another bugs that cause panics described in the two PRs, but
now we can examine them more easily :).
