[SCSI] aacraid: superfluous adapter reset for IBM 8 series ServeRAID controllers 

The kexec patch introduced a superfluous (and otherwise inert) reset of
some adapters. The register can have a hardware default value that has
zeros for the undefined interrupts. This patch refines the test of the
interrupt enable register to focus on only the interrupts that affect
the driver in order to detect if an incomplete shutdown of the Adapter
had occurred (kdump).
