scsi: BusLogic: Fix 64-bit system enumeration error for Buslogic

[ Upstream commit 56f39614 ]

Commit 391e2f25 ("[SCSI] BusLogic: Port driver to 64-bit")
introduced a serious issue for 64-bit systems.  With this commit,
64-bit kernel will enumerate 8*15 non-existing disks.  This is caused
by the broken CCB structure.  The change from u32 data to void *data
increased CCB length on 64-bit system, which introduced an extra 4
byte offset of the CDB.  This leads to incorrect response to INQUIRY
commands during enumeration.

Fix disk enumeration failure by reverting the portion of the commit
above which switched the data pointer from u32 to void.
