data_access_emulation() may fault. Be sure to clear pcb_onfault before
invoking it.
While there, rework the return-to-pcb_onfault logic to avoid falling through
the DAE code. This allows us to get rid of the bogus DMT_SKIP flag as well:
DAE is only necessary if DMT_VALID is set in DMT0, and DMT0 is reset to zero
afterwards.
