[PATCH] libata: move BMDMA host status recording from EH to interrupt handler

For certain errors, interrupt handler alter BMDMA host status before
entering EH (clears active and intr).  Thus altered BMDMA host status
value is recorded by BMDMA EH and reported to user.  Move BMDMA host
status recording from EH to interrupt handler.
