scsi: megaraid_sas: In probe context, retry IOC INIT once if firmware is in fault

Browse source

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.
