[PATCH] SCSI: sgiwd93: Convert to use shost_priv()

[Ralf Baechle <ralf@linux-mips.org>]

The driver had its own similar macro and still one open-coded reference
to ->hostdata.  Use shost_priv() everywhere for consistency.

Build tested only - I don't have a test system at hand atm.

The previous patch was missing a Signed-off-by: line, feel free to add it.
