scsi: mpt3sas: Transition IOC to Ready state during shutdown
The IOC firmware assumes that the host driver is still alive after shutdown and continues to post events to host memory (due to faulty expander phy links, etc). This leads to 0x2666 (a bus fault occurred during a host-IOC memory access). Perform an IOC soft reset as part of shutdown to disable event posting.
