wdk 505a7027b6 Revert back to invalidating cache during BUS_DMASYNC_POSTREAD instead of
during BUS_DMASYNC_PREREAD.

Fixes problem where SCSI bus probe didn't read meaningful identity data.

Technically there should be no difference between invalidating before or
after the DMA, but for reasons known only to the R3000 this fixes the
problem.   Some thought needs to be given to whether there is a performace
difference between these two cases.
