scsi: aic7xxx: aic79xx: fix potential null pointer dereference on ahd

Browse source

If AHD_DEBUG is enabled and ahd_platform_alloc fails then ahd is set to
null and the debug printk dereferences ahd when passing it to ahd_name.
Fix this by moving the debug printk to before the call to
ahd_platform_alloc where ahd is not null at that point.
