[SCSI] qla2xxx: Correct inadvertent clearing of RISC_INTR status.
During heavy I/O (CPU-affinity mode enabled) and CLI/Agent interactions, the driver would report periodic mailbox command timeout statuses. Within the CPU-affinity ISR handler, the driver should check the 'disable-msix-handshake' flag in deciding whether or not to clear HCCRX_CLR_RISC_INT. The mode is not specific to a dedicated queue, instead, applies to the current 'ha' context.
