scsi: megaraid_sas: In probe context, retry IOC INIT once if firmware is in fault
Issue: Under certain conditions, controller goes in FAULT state after IOC INIT fired to firmware. Such Fault can be recovered through controller reset. Fix: In driver probe context, if firmware fault is observed post IOC INIT, driver would do controller reset followed by retry logic for IOC INIT command.
