[SCSI] mpt2sas: Fix for issue - Unable to boot from the drive connected to HBA
This patch checks whether HBA is SAS2008 B0 controller.
if it is a SAS2008 B0 controller then it use IO-APIC interrupt instead of MSIX,
as SAS2008 B0 controller doesn't support MSIX interrupts.
[jejb: fix whitespace problems]
