Fix DAR/DSISR reading before they are written

If the DAR and DSISR are read before they are written, we assert with:

  register_file.vhdl:55:25:@60195ns:(report note): Writing GPR 09 00000000XXXXXXXX
  register_file.vhdl:61:17:@60195ns:(assertion failure): Assertion violation

This initialises DAR/DSISR to avoid this.
