[SCSI] hpsa: fix redefinition of PCI_DEVICE_ID_CISSF

PCI_DEVICE_ID_CISSF is defined as 323b in pci_ids.h but redefined as 3fff in
hpsa.c. The ID of 3fff will _never_ ship as a standalone controller. It is
intended only as part a complete storage solution. As such, this patch
removes the redefinition and the StorageWorks P1210m from the product table.

It also removes a duplicate line for the "unknown" controller support.
