[PATCH] fix compile regression for a few scsi drivers

This fixes three drivers to compile again after my patch that removes
the data_cmnd member from struct scsi_cmnd.

The fas216 change is trivial, it should have been using ->cmnd all the
time.

NCR53C9 (which seem to be mostly duplicate driver with esp.c!) is doing
something odd, it should only have looked at ->cmnd before not the saved
copy that is kept for the error handlers sake.  Note that it really
should deal with the sync setting themselves but use the generic domain
validation code that get this right - but that's for later let's push
this simple compile fix for now.

And sorry for the late fix for this, I have been busy with OLS and
associated activities last week.
