[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).
