[SCSI] qla2xxx: Workaround D3 power-management issues.
Early ISP2432 parts have a known hardware issue when coming out of a D3 hot state. This issue can result in a hung PCIe link. Recent firmwares contain a workaround whereby the stop-firmware mailbox command prevents the ISP from entering the D3 hot state. In order to ensure that the workaround succeeded the driver must verify that the stop-firmware mailbox command completes successfully. In the event of a failure, the driver attempts a shutdown-retry after resetting the ISP and re-executing firmware.
