scsi: mpt3sas: Handle firmware faults during first half of IOC init
During first half of IOC initialization (i.e. before going for device scanning), if any firmware fault occurs then driver is aborting the IOC initialization operation. Modify the driver to issue a diag reset operation to recover IOC from fault state and reinitialize the IOC.
