scsi: mpt3sas: Handle firmware faults during first half of IOC init

Browse source

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.
