target/nios2: Cleanup set of CR_EXCEPTION for do_interrupt

The register is entirely read-only for software, and we do not
implement ECC, so we need not deposit the cause into an existing
value; just create a new value from scratch.

Furthermore, exception.CAUSE is not written for break exceptions.
