[PATCH] fix compile regression for a few scsi drivers

[PATCH] fix compile regression for a few scsi drivers

[Christoph Hellwig]

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.

esp and NCR53C9 which seem to be mostly duplicate drivers (!) are doing
something odd, they should only have looked at ->cmnd before not the
saved copy that is kept for the error handlers sake.   Note that they
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 sorrt for the late fix for this, I have been busy with OLS and
associated activities last week.
