Restore proper use of bounce buffers for ISA DMA.  When locking was
added, the call to pmap_kextract() was moved up, and as a result the
code never updated the physical address to use for DMA if a bounce
buffer was used.  Restore the earlier location of pmap_kextract() so
it takes bounce buffers into account.
